• 24/7: A relationship in which protocols are in place continuously.
• Animal transformation fantasy: Fantasy in which the focus is on the sub entering the altered mindspace of a different species, typically a dog, pony or horse.
• Abrasion: Using something rough (such as sandpaper).
• Aftercare: The time after a BDSM scene or play session in which the participants calm down, discuss the previous events and their personal reactions to them, and slowly come back in touch with reality. BDSM often involves an endorphin high and very intense experience, and failure to engage in proper aftercare can lead to subdrop as these return to more everyday levels.
• Ageplay: Usually referring to daddy/daughter or mommy/baby role play. Does not usually include or imply aspects of incest, but rather the nurturing relationship of parent/child or teacher/student.

• Animal Play: The sub acts or dresses like an animal (puppy, pony, cow, etc.).
• Auctioned off: Dominant auctions off the slave to the highest bidder (usually supervised and for temporary use).
• Bad pain (1): Good pain and bad pain are terms used lightheartedly by BDSM practitioners, signifying that whilst BDSM may include an element (often quite pronounced) consensual pain, there is a purpose to it, and some pain is consented to and accepted whilst other pain is not. "Bad pain" is pain which is outside hard limits, non-mutual or non-valued, not wished for, and of limited or no value in this context.
• Bad pain (2): Good pain and bad pain refer to pleasant vs. unpleasant pain. As a "vanilla" example, imagine soreness after a good workout at the gym versus the pain of breaking a leg. Research by Jay Wiseman has suggested a correlation between perception of "bad pain" during BDSM play and subsequent injury.
• BDSM: Bondage/Discipline, Dominance/Submission, Sadism/Masochism
• Black sheet party: An orgy for people into BDSM sex.
• Bondage: Acts involving the physical restraint of a partner. Bondage typically refers to total restraint, however it can be limited to a particular body part, such as breast bondage.
• Bottom: submissive or one who gives up control, or simply one who receives physical sensation from a top in a scene.
• Breast bondage: The act of tying female breasts so that they are either flattened against the chest or so that they bulge.
• Breath Control: The dominant controls the submissive's breathing.
• Butt plug: Much like a dildo, only shaped slightly differently. The flared base allows for safe anal penetration. They come in a variety of sizes; some can vibrate.
• Chastity: A form of erotic sexual denial or orgasm denial whereby a person is prevented from access to, or stimulation of, their genitals, save at the whim or choice of their partner, usually by means of a device (called a chastity belt or sometimes for men a cock cage) that prevents contact and is controlled by means of a lock by the partner.
• Cock and ball torture (CBT): Torture of the male genitals for sexual gratifcation.
• Collared: Submissive or slave who is owned, usually (but certainly not exclusively) in a loving intimate relationship. A dominant may have multiple persons collared. Also: a pup's status, as differentiated from a "stray".
• Collaring: The formal acceptance by a Master, of a slave's service, or the "ownership" of a pup by a Master or Trainer. Also the ceremony when a dominant commits to a sub (much like a wedding or other contract).
• Consent: Mutual agreement to the terms of a scene or ongoing bdsm relationship.
• Consensual non-consensuality: A mutual agreement that within defined limits, or subject to a safe word or other restrictions, and common sense, consent will be given as read without foreknowledge of the exact actions planned. As such, it is a show of trust and understanding and usually undertaken only by partners who know each other well, or otherwise agree to set clear safe limits on their activities.
• Contract: A written-out agreement between the dominant & submissive. It can be either formal or non, and is usually written after much negotiation by the dominant and the sub, outlining what structure, guidelines, rules and boundaries to the relationship are agreed upon by the two. It is not legally binding.
• DM: Dungeon Monitor, a person who volunteers to supervise the interactions between participants at a play party to ensure their safety.

• Dominant Man or woman who exercises control - contrast with submissive
• Domme: Woman who exercies control (see also Dominatrix)
• D/s: Dominance/submission
• Dungeon: Usually referring to a room or area with BDSM equipment and play space
• Edgeplay: SM play which pushes the limits of the persons involved. This can be potentially dangerous activities such as fire, electricity, cutting, or breath play. Skill and experience can minimize the risk.
• Endorphin rush: Endorphins are the chemicals responsible for the "high" people often get from activities such as sex, or high-risk sports, and is the body's response to heightened or intense experiences of certain kinds. BDSM activities, especially those incorporating a degree of sensation play often cultivate the endorphin rush as part of their "payoff" to the sub. But also see aftercare for the care needed to ensure that subdrop does not occur afterwards as the body returns to normal.
• Erotic sexual denial: keeping another person aroused while delaying or preventing resolution of the feelings, to keep them in a continual state of anticipatory tension and inner conflict, and heightened sensitivity. (see also tease and denial and chastity).
• Fetish: A specific obsession or delight in one object or experience.
• Fire play: Using flammable liquids to create quick, fleeting instances of flame on the skin of the bottom. Risk of injury is increased and the top should be learned with fire play skills.
• Genitorture: Torture of the genitals
• Good pain (1): Good pain and bad pain are terms used lightheartedly by BDSM practitioners, signifying that whilst BDSM may include an element (often quite pronounced) of consensual pain, there is a purpose to it, and some pain is consented to and accepted whilst other pain is not. "Good pain" is therefore pain that is mutually agreed, desired or permitted by the submissive partner to be experienced, and seen by them as of enjoyment or value.
• Good pain (2): Good pain and bad pain refer to perception of pain as pleasant vs. unpleasant. Sensations that non-practioners imagine to be painful are instead perceived and described by BDSM practitioners as pleasurable or a good form of pain, in much the way that muscles after a workout at the gym may be sore, but in a good way. The transition of perception from "bad pain" to "good pain" may require a warm up beforehand.
• Golden showers: Urinating on, or being urinated on by, another person.
• Gorean: A sub-genre based upon the rituals and practices created within the world of Gor in the erotic novels by John Norman.

The slave will usually accept a collar from their Master to show that they are owned.
• Mummification: Immobilising the body by wrapping it up, usually with multiple layers of tight thin plastic sheeting. Breathing and other safety measures must be appropriately taken care of, often by leaving the face (or at least the mouth and nose) open. Body temperature (maintained to an extent by movement) may also be affected so a warm environment and warm aftercare may be important. Mummification is often used to enhance a feeling of total bodily helplessness, and incorporated with sensation play.
• Munch: A group of people that are into BDSM meeting at a "vanilla" place. Sometimes this is a club. You might see an announcement like, "This weekend's munch is at Denny's"

• Slave: A person (usually submissive) who consensually gives up total control of one or more aspects of their life to another person (their Master)

• Subdrop: A physical condition, often with cold- or flu-like symptoms, experienced by a submissive after an intense session of BDSM play. This can last for as long as a week, and is best prevented by aftercare immediately after the session.

• Subspace: A "natural high" that a sub (or bottom) gets during a scene or when being controlled.

It is critical that a Dom(me)/top take responsibility for the sub/bottom and be aware of their sub's wellbeing if they are in subspace.
• switch: Someone who likes being both top and bottom, either in one scene or on different occasions.
• Taken in hand: 24/7 Male dominance in monogamous marriage, with or without BDSM aspects.

• Wax play: The top drips hot wax on the bottom.

Note that some people in the BDSM community begin dominant terms with an upper case, for example: Top, Master, Dom, Domme, etc., as well as to begin submissive terms with a lower case, even where normally incorrect, chiefly in acronyms and abbreviations, such as D/s for Dom/sub.
