Kink glossary: 46 terms, explained plainly

Consent & safety

Consent

A clear, freely given, informed and ongoing “yes” from every adult involved. Consent is specific (yes to one thing is not yes to everything), can be withdrawn at any moment, and cannot be given by someone who is pressured, asleep or too intoxicated to decide. In kink it is the foundation everything else rests on.

Negotiation

The conversation partners have before any play: what each person wants, what is off the table, how to stop, health and safety needs, and what aftercare looks like. Good negotiation happens sober, ahead of time, and with no pressure to agree.

Limits (hard & soft)also: hard limit, soft limit

Boundaries around what someone will and will not do. A hard limit is a firm “never”: it is not up for discussion in the moment. A soft limit is a “maybe, carefully” or “not yet”: something a person might explore slowly, only with prior agreement. Limits can change over time, and they are always respected.

Safeword

A word or signal agreed in advance that immediately stops or pauses play, no questions asked. It is usually something that would not come up naturally (“red” or “pineapple”). When speaking is not possible, partners agree a non-verbal signal instead, such as dropping an object or tapping out.

Traffic-light systemalso: green / yellow / red

A simple, popular set of safewords. Green means “all good, keep going”, yellow means “slow down or check in”, and red means “stop now”. It makes check-ins quick and easy, even in the middle of a scene.

Check-in

A quick question during or after play to confirm someone is still okay: “How are you doing?”, “Color?”, “Want more or less of this?”. Regular check-ins keep consent ongoing rather than a one-time agreement.

SSCalso: Safe, Sane and Consensual

One of the oldest kink community frameworks: activities should be safe, approached with a sound state of mind, and fully consensual. Many people now pair it with RACK or PRICK because no activity is perfectly “safe”.

RACKalso: Risk-Aware Consensual Kink

A framework that admits all play carries some risk and asks everyone to understand those risks, talk about them openly, and consent knowing what they are agreeing to.

PRICKalso: Personal Responsibility, Informed Consensual Kink

A framework that builds on RACK by stressing that each person is responsible for learning about what they do, speaking up about their own needs and limits, and making informed choices.

Aftercare

The care partners give each other after a scene: water, a blanket, a snack, cuddles, quiet time, talking it through, or checking in the next day. Everyone involved can need aftercare, not just the person on the receiving end, and it is part of negotiation.

Drop (sub drop / top drop)also: sub drop, top drop, Dom drop

A low mood, tiredness or emotional dip that can follow an intense scene, sometimes hours or days later, as adrenaline and other feel-good chemicals wear off. It can affect anyone who took part. Aftercare, rest and a follow-up check-in help.

CNCalso: consensual non-consent

An advanced form of roleplay where adults agree, in detail and well in advance, to act out a scene in which one partner plays at resisting. The real consent is given beforehand during careful negotiation: limits are set, a safeword or signal stays active the whole time, and anyone can stop at any moment. It needs deep trust and experience, is not for first meetings, and is never a cover for anything that was not agreed.

Safe callalso: safety call

An arrangement with a trusted friend before meeting someone new: you tell them where you will be and who you are meeting, and check in at a set time. If you do not check in, they know to call or get help.

Vetting

Taking reasonable steps to check that a new partner is who they say they are and has a good reputation: chatting first, a video call, meeting in public, or asking people in the community who know them. Vetting goes both ways.

Roles & dynamics

Top / bottom

In kink, the top is the person doing the action (for example, tying the rope) and the bottom is the person receiving it. These describe what happens in a scene and are not the same as who holds authority; that is Dom/sub.

Dom / subalso: Dominant / submissive, D/s

A consensual power exchange in which one partner (the Dominant) takes the lead and the other (the submissive) chooses to follow, within limits both agreed. The submissive’s consent and limits shape the whole dynamic. A D/s dynamic can last for one scene or be part of an ongoing relationship.

Power exchange

Any dynamic where partners consensually agree that one person will hold more control than the other for a time, inside agreed rules. It ranges from playful and occasional to structured and ongoing.

Switch

Someone who enjoys both roles, sometimes leading or topping and sometimes following or bottoming, depending on the partner, the mood or the activity.

Bratalso: brat tamer

A playful submissive who teases, pushes back or “misbehaves” on purpose because both partners enjoy the game of being put back in line. The partner who enjoys that game is often called a brat tamer. Bratting is consensual fun, not real disrespect of limits.

Primalalso: primal play

Play focused on instinct rather than words or rules: chasing, wrestling, growling and physical playfulness. People often describe themselves as primal predators or primal prey. Like any play, it is negotiated first.

Protocol

Agreed rules or rituals within a dynamic, such as particular forms of address, how a scene starts or ends, or daily check-ins. Protocol can be very formal or very light, and partners design it together.

Collaringalso: collar

A ceremony or gesture in which a submissive accepts a collar (or a discreet symbol like a necklace or bracelet) to mark a committed D/s relationship. Its meaning is whatever the partners agree, and it can be compared to exchanging rings.

Subspacealso: topspace

A floaty, deeply relaxed or euphoric state some bottoms experience during intense play. Someone in subspace may not be able to judge limits well, so partners lean on prior negotiation and non-verbal signals. Tops can feel a focused “topspace” too.

Play partner

Someone you do kink with, by agreement. A play partner may or may not also be a romantic or sexual partner; partners decide together what the relationship includes.

Kinds of play

Scene

Two meanings. A scene is a single, negotiated session of play with a start and an end. “The scene” also means the wider kink community.

Rope bondage / shibarialso: kinbaku

Using rope to restrain or decorate a willing partner. Shibari and kinbaku are Japanese-influenced styles known for their patterns and aesthetics. Rope needs real skill: learn from classes or experienced people, avoid nerve and circulation injuries, check in often, and keep safety shears close by.

Impact play

Play involving consensual striking, from light spanking to the use of paddles or floggers. Safe impact play avoids vulnerable areas such as the spine and kidneys, builds up gradually, and uses clear check-ins.

Sensation play

Exploring different physical sensations, such as feathers, ice, warmth, textures or a blindfold that heightens other senses. It is a gentle, popular starting point for people new to kink.

Roleplay

Partners acting out agreed characters or scenarios for fun or fantasy. Like everything else, the characters, the limits and how to step out of the roleplay are agreed beforehand. On Sparks, all roles and scenarios involve adults only.

Edge play

A loose term for activities that carry more physical or emotional risk than most, or that sit at the edge of someone’s comfort. It calls for education, experience, very careful negotiation and a lot of trust. What counts as “edge” varies from person to person.

Community & etiquette

Vanilla

Sex or relationships without kink, or a person who is not into kink. It is a description, not an insult, and plenty of people on Sparks are happily vanilla.

Kink vs fetishalso: kink, fetish

A kink is any consensual sexual or intimate interest outside what is seen as conventional. A fetish usually means a strong focus on a specific object, material or body part, sometimes to the point that it is important for arousal. People often use the two words loosely and interchangeably.

Munch

A casual, public, no-play social meetup for kink-curious and kinky adults, usually at a restaurant, café or bar. It is the classic low-pressure way to meet people in the community. Normal clothes, normal conversation, no play.

Munch etiquette

The unwritten rules of munches: wear everyday clothes, use scene names if people prefer them, do not out anyone or share who attended, do not take photos of other people, do not treat it as a hookup venue, and do not touch anyone without asking.

Play partyalso: dungeon

An organized private event where adults can do kink in a space set up for it, usually with house rules, consent policies and volunteers watching for safety. A dungeon is a venue equipped for play.

Dungeon monitor (DM)also: DM

A volunteer at a play party or dungeon who watches for safety and rule-following, steps in if someone calls a safeword that is not respected, and helps in an emergency.

FetLife

A long-running social network for the kink community, widely used to find munches, classes and events. It is a separate site and is not connected to Sparks.

YKINMKalso: Your kink is not my kink (and that’s okay)

Community shorthand for respecting other people’s consensual interests without judgement, even if they are not for you. Not yucking someone else’s yum.

Relationships & ENM

ENMalso: ethical non-monogamy, CNM

An umbrella term for relationship styles where everyone involved knows about and agrees to romantic or sexual connections with more than one person. Honesty and consent are what make it “ethical”. Also called consensual non-monogamy (CNM).

Polyamoryalso: poly

Having, or being open to, more than one loving relationship at the same time, with the knowledge and consent of everyone involved.

Open relationship

A relationship where partners agree they can have sexual or casual connections with other people, often while keeping their own relationship as the main romantic one. The specific rules vary couple to couple.

Swingingalso: the lifestyle

A form of non-monogamy, usually among couples, focused on recreational intimacy with other people, often at social events. Many swingers call it “the lifestyle”.

Unicornalso: unicorn hunting

Usually a single person, often a bisexual woman, who dates or plays with an existing couple. “Unicorn hunting” is when a couple searches for one, and it is often criticized when the couple expects the third person to fit rules they had no say in. Respectful couples treat a third as a full person with their own needs and limits.

Compersion

Feeling happy because a partner is happy with someone else. It is often described as the opposite of jealousy, though many people feel both at different times.

Metamour

Your partner’s other partner. You are not dating each other, but you are connected through someone you both care about.

Nesting partner

A partner you live with or share a home and daily life with, in a non-monogamous setup.
