When Matt and I were first getting curious about the lifestyle, I remember reading forum posts and feeling like I’d stumbled into a conversation happening in a foreign language. Soft swap? Full swap? Unicorn? Hall pass? I’d nod along like I understood and then immediately Google everything afterward.
Nobody should have to do that.
This glossary is the resource I wish I’d had when we were starting out — a plain-English breakdown of the terms, phrases, and acronyms you’ll encounter in the swinging community. Bookmark it. Reference it. Share it with your partner so you’re both working from the same definitions before you have The Big Conversation.
One note before we dive in: terminology isn’t always universal. Different communities, regions, and even individual couples use some of these terms slightly differently. What matters most is that you and your partner are clear on what these words mean to you.
A
Adult Lifestyle / The Lifestyle The most common umbrella term for the swinging community. When someone says they’re “in the lifestyle” or “lifestyle-friendly,” they’re signaling they’re open to or actively participating in consensual non-monogamy with other couples or singles. It’s the preferred term in the community because it’s inclusive and sounds less like a 1970s Hugh Hefner special.
Age Play Sexual roleplay involving age dynamics. Not to be confused with anything involving minors — this refers exclusively to adults roleplaying. You’ll see this term in kink communities more than swinging communities, but there’s significant overlap.
Aftercare The time and attention partners give each other after a sexual or emotionally intense experience. Can include cuddling, checking in verbally, getting food, or just talking. More common language in BDSM circles, but increasingly used in lifestyle conversations too. Matt and I have our own version — takeout and a long debrief. Highly recommend.
Afterparty An informal gathering that continues after a lifestyle event or club night, often at someone’s home. Usually smaller and more intimate than the main event. Invitations are typically extended only to people who connected well during the event.
B
Bi-curious Someone who is primarily straight but open to or interested in same-sex experiences. Common in the lifestyle, especially among women. If you’re bi-curious, you’ll find the lifestyle community generally very welcoming.
Bisexual Attracted to both men and women. In lifestyle contexts, often abbreviated as “bi” in profiles. Bisexual women are extremely common in the lifestyle. Bisexual men less so, though this is changing — slowly.
Body Image / Body Positivity Worth mentioning here because it comes up constantly. The lifestyle community is far more accepting of diverse body types than mainstream culture would have you believe. People of all shapes, sizes, and ages participate. If you’re worried you don’t look like a porn star, take a breath — most people in the lifestyle don’t, and it doesn’t matter.
BBW Big Beautiful Woman. A term used in profiles to describe fuller-figured women, used either as self-identification or as a preference noted by potential partners.
C
Closed Swap See Full Swap — sometimes used interchangeably, though “closed swap” can also specifically mean the full swap happens in a private space rather than with the other couple present. The terminology varies.
Club (Lifestyle Club / Swing Club) A venue specifically designed for lifestyle socializing and play. Can range from hotel takeover events to permanent venues with play spaces, hot tubs, and social areas. Most have membership or vetting requirements. Our first experience was at a lifestyle club in Phoenix — awkward, chaotic, and also kind of wonderful.
Consent Not really lifestyle-specific jargon, but worth defining here because it’s the foundation of everything. In the lifestyle, consent means enthusiastic, ongoing, revocable agreement to any activity. “No” always means no. “Maybe later” isn’t a yes. This community takes it seriously — people who don’t get asked to leave.
Couple’s Privilege A concept that comes up more in polyamory discussions but bleeds into swinging too. Refers to the tendency of established couples to prioritize their relationship in ways that can feel limiting or unfair to third parties (singles, especially). Good to be aware of, especially if you start connecting with singles.
Cowboy / Cowgirl A single person who enters a relationship with a couple with the intention of pulling one partner away from the relationship. Not a compliment. If someone warns you about a “cowboy,” they’re flagging potentially predatory behavior.
D
DNR Do Not Resuscitate — just kidding. In the lifestyle, DNR means Do Not Repeat or, more often, Did Not Connect. Used informally to describe a couple or situation that just didn’t work out and you won’t be pursuing again. Not mean-spirited — just practical. Not every connection is a match, and that’s fine.
Dress Code Lifestyle events often have specific dress codes — lingerie and robes, all-black, formal/black tie, costume themes. This isn’t just about aesthetics; it signals that you’re there intentionally and helps set the mood. Check the event details before you show up in jeans when everyone else is in lingerie. (Don’t ask how I know to mention this.)
E
ENM (Ethical Non-Monogamy) The overarching term for relationship structures that involve consensual romantic or sexual connections beyond a primary couple. Swinging falls under this umbrella, as do polyamory, open relationships, and relationship anarchy. The “ethical” part is important — it distinguishes consensual arrangements from cheating.
F
Fluffer In the lifestyle, this term is sometimes used casually to refer to someone who helps warm up the mood at an event — telling stories, breaking the ice, easing nerves. It also has a more explicit meaning you can look up yourself. Context usually makes clear which one is meant.
FMF / MFM Three-person configurations. FMF = female-male-female threesome. MFM = male-female-male threesome. These are not the same as FFM or MMF in terms of how participants often talk about their comfort level with same-sex contact. In an MFM, the two men are typically not interacting with each other. In an MMF, they might be. Always clarify what people mean rather than assuming.
Fluid Bonded Being sexually active with a partner without barrier protection — i.e., without condoms. Fluid-bonded partners have made an explicit agreement about this after STI testing. The term is important in lifestyle circles because most couples are fluid-bonded with each other but use protection with play partners.
Full Swap When both members of a couple engage in penetrative sex with the other couple’s partners. The most commonly searched lifestyle term, and the one that most beginners spend a lot of time deciding how they feel about. Many couples start with soft swap and eventually move to full swap. Many don’t, and that’s completely valid.
G
Green Light A signal — verbal or nonverbal — that you’re comfortable and interested in proceeding. Part of good lifestyle etiquette is watching for and giving clear signals rather than assuming.
H
Hall Pass Permission granted by one partner for the other to have a sexual encounter solo, without the other partner present. Different from swinging in that it’s not a shared experience — one partner is “off on their own.” Some couples use this occasionally; others would never. No wrong answer.
HH / HHH Hot Husband/Hubby (or Hot Hot Husband, depending on who you ask). Used in profiles, similar to HW for Hot Wife. Signals that the couple finds the husband attractive and wants that acknowledged.
Hot Wife / Hotwife A woman in a relationship who has her partner’s encouragement and blessing to have sexual experiences with others, sometimes while the partner watches or is informed afterward. Distinct from swinging in that it’s often more one-directional — the focus is on her experiences. Some couples in the lifestyle identify with this dynamic; others don’t.
HW Hot Wife. You’ll see this in profiles constantly.
I
In the Lifestyle / Lifestyle-Friendly Shorthand for being part of or open to the swinging community. When someone says they’re “lifestyle-friendly” in a dating profile or introduction, they’re signaling openness to connecting with other swingers.
J
Jealousy Not a swinging term per se, but the thing nobody talks about enough. Jealousy is normal. It doesn’t mean you’re doing it wrong or that swinging isn’t for you. Matt and I have both dealt with it, in different ways and at different times. The lifestyle community generally acknowledges jealousy as something to work through, not ignore or shame.
L
LS / Lifestyle Shorthand abbreviations for “lifestyle.” You’ll see “LS couple,” “LS friendly,” and “LS community” frequently in profiles and forums.
Lifestyle Club See Club.
M
Meet and Greet (M&G) A casual social gathering — often at a bar or restaurant — where lifestyle couples meet potential connections in a low-pressure environment. No play happens at meet and greets. It’s the preview, not the show. Great entry point for curious couples who want to test the waters socially before committing to a full event.
Monogamish A term popularized by sex columnist Dan Savage for relationships that are primarily monogamous but allow for occasional exceptions with agreed-upon rules. Many swinging couples would describe their relationship this way.
N
NRE (New Relationship Energy) That intoxicating rush of excitement you feel when you’re connecting with someone new. Common in both polyamory and swinging circles. Worth knowing about because NRE can cloud judgment and make new connections feel more significant than they are in the long run. Matt and I have a rule: no major decisions in the middle of NRE.
O
On Premise An event or venue where play (sexual activity) can happen on-site. As opposed to “off premise,” where the event is social but any play happens elsewhere afterward. Lifestyle clubs are typically on-premise. Many meet-and-greet events are off-premise.
Off Premise Social lifestyle events where sexual activity isn’t permitted at the venue itself. Great for first-timers — all the social benefits, lower pressure.
Open Relationship A relationship structure where both partners are free to have other romantic or sexual connections, with mutual knowledge and consent. Overlaps with swinging but isn’t identical. Swinging typically refers specifically to recreational sex with other couples; an open relationship might involve deeper romantic connections.
P
Play The lifestyle’s most common euphemism for sexual activity. “Play partners” are couples or individuals you hook up with. “Playroom” is where the action happens at a lifestyle club. “Looking to play” in a profile means they’re actively seeking sexual connections. You get the idea.
Play Partner A couple or person you engage sexually with in a lifestyle context. Play partners range from one-time connections to ongoing “friends with benefits” arrangements. Unlike polyamorous partners, play partners are typically not romantic or emotionally entangled.
Poly / Polyamory A relationship structure involving multiple romantic and/or sexual partners with everyone’s knowledge and consent. Often confused with swinging, but distinct — polyamory typically involves deeper emotional connections alongside (or instead of) the sexual ones. There’s significant crossover in the community, but they’re different lifestyles.
Profile Your presence on a lifestyle dating site or app. A good profile is your calling card in the online LS community. We’ve got a whole guide on writing a great one if you need it.
R
Recroom / Playroom The designated space at a lifestyle club or private party where sexual activity takes place. Can range from a single room with mattresses to elaborate multi-room setups. House parties often have a designated bedroom or two. It’s usually obvious.
S
Safe Call A prearranged check-in call with a trusted friend when you’re meeting strangers. You share your location, a description of who you’re meeting, and agree on a check-in time. If you don’t call back, your friend knows something’s off. Nicole’s safety non-negotiable: always do a safe call when meeting a new couple for the first time.
Safe Sex / Safer Sex The lifestyle community varies in how strictly members adhere to barrier protection. Most on-premise clubs require condoms for penetrative sex. Many experienced lifestyle couples practice “safer sex” — using condoms with play partners, getting regular STI testing, being honest about status. If someone is casual about this, pay attention.
Same Room / Same Room Sex When two couples play in the same room, even if they’re each engaging with their own partner. Some couples enjoy the energy of this without actually swapping partners. It’s a comfortable middle ground.
Soft Swap Sexual play with another couple that stops short of penetrative sex. Typically includes kissing, touching, oral sex, and other activities — just not intercourse. Many couples start here and decide either to stay here (perfectly valid) or eventually move to full swap. If you see “soft swap only” in a profile, they’ve set that as their limit and mean it.
Solo Play Playing independently, without your partner present. Either with a third party (see Hall Pass) or self-directed. Some couples incorporate this into their lifestyle arrangement; others don’t.
STI Testing Sexually transmitted infection testing. The responsible, adult expectation in the lifestyle. If someone refuses to discuss their testing status or gets cagey about it, that’s a red flag. Matt and I test every three months and consider this non-negotiable.
Stag / Vixen A specific dynamic where the male partner (the “stag”) enjoys watching or knowing about his female partner (the “vixen”) having experiences with others. Related to but distinct from the hot wife dynamic. The stag is typically actively engaged in facilitating and enjoying the dynamic rather than just tolerating it.
Swinging The practice of a committed couple engaging in consensual sexual activity with other couples or singles, typically for recreational purposes rather than romantic ones. That’s the textbook definition. The reality is messier, more human, and considerably more interesting.
Swinger A person who participates in swinging. Also: us. (Hi.)
T
Takeout Rule / Two Week Rule An informal guideline some couples use: after a new experience, wait two weeks before making any major relationship decisions. Feelings — good and bad — can be intense immediately after a new experience, and giving yourself time to process helps separate the emotional spike from reality.
Threesome A sexual encounter involving three people. In lifestyle contexts, the most common configurations are FMF (two women, one man) and MFM (two men, one woman). Less common but not unheard of: three couples mixing, or other configurations entirely.
Towel (Bring a Towel) Practical lifestyle club advice. Just bring one. You’ll understand when you get there.
U
Unicorn A single bisexual woman willing to join a couple for a threesome or ongoing arrangement. Called a “unicorn” because, in the lifestyle community’s experience, they’re rare — and the demand far exceeds the supply. If you’re hoping to find one, you’ll need to approach this with genuine respect for her as a full human being, not a bonus feature for your relationship. Women in the lifestyle community have Strong Feelings about how couples treat single women, and rightfully so.
Unicorn Hunters A couple — often the woman is bi-curious rather than bisexual — seeking a unicorn, sometimes with unrealistic expectations or treating potential thirds as accessories rather than people. This term is often used critically in the community. Approaching the lifestyle this way tends not to go well. Be the couple that earns trust, not one that earns an eye-roll.
V
Vetting The process of getting to know and verifying potential play partners before meeting in person. Can involve phone calls, video chats, checking references from other couples who know them, or reviewing their history on lifestyle sites. Vetting is not paranoia — it’s how you stay safe and find genuine connections.
W
Wristband System Many lifestyle clubs use colored wristbands to signal preferences and availability. Common color codes vary by venue, but often something like: green (open and interested), yellow (look but don’t approach), red (not available/playing with current partner only). Always check the specific event’s wristband code when you arrive. This system is a genuine kindness — saves everyone from awkward guessing.

A Few Final Thoughts
Learning the language of the lifestyle is the easy part. The harder work — the conversations with your partner, the boundary-setting, the emotional preparation — that takes time and honesty. But knowing the vocabulary at least means you won’t be nodding along pretending to understand what “soft swap only, on-premise preferred” means when you’re reading profiles at 11pm.
If you’re just starting out, I’d also recommend reading our Beginner’s Guide to Swinging for a broader overview of how to get started. And if you’ve been in the lifestyle a while and noticed a term I missed, drop a comment. The language evolves, and I’m always adding to this.
Welcome to the lifestyle. We’re glad you’re here.
