Dictionary of BDSM Terms

This glossary is a guide to many of the terms you might hear in the BDSM community. Not everyone who is involved with BDSM is into everything listed here; many of the practices described in the Glossary are quite rare. If you see something described in here which isn't to your tastes, it doesn't mean that you aren't or can't be interested in BDSM.

The definitions given here reflect the usage I am most familiar with. Some terms contain commentary; anything following the word Commentary indicates my own views on a particular subject, and should not be assumed to be part of the formal definition.

Links in the definitions will take you to other definitions on this page unless the links are in »angle quotes«, in which case they will take you off this page.

AFTERCARE: A period of time after intense BDSM activity in which the dominant partner cares for the submissive partner. Commentary: Some BDSM activities are physically challenging, psychologically intense, or both. After engaging in such activities, the submissive partner may need a safe psychological space to unwind and recover. Aftercare is the process of providing this safe space.

Commentary: One common misperception about age play is that it appeals to pedophiles or is intended to simulate pedophilia.

BOTTOM: A person who receives spankings, floggings, or other forms of stimulation in situations which specifically exclude power exchange. For example, a masochist may be interested in receiving some kind of stimulation but may not be interested in giving up psychological control; whereas a submissive has given up authority and may receive some kind of stimulation on the instruction of a dominant, a bottom does not give up authority and may control exactly how, under what circumstances, and to what degree he or she receives some form of stimulation. Contrast top; see related submissive.

BOTTOM DROP: Colloquial A sudden, abrupt feeling of depression, unhappiness, or similar negative emotion in a submissive which may occasionally occur immediately after a period of BDSM activity.

Often considered an extremely dangerous form of edge play (def. 1), as it can and often does lead to permanent injury or death. Also referred to as asphyxia, erotic asphyxiation, gasping. See related auto-erotic asphyxia.

BREEDING FETISH; also, IMPREGNATION FETISH: A type of sexual expression centered around a fixation on impregnating a woman, which may also include fixation on other things normally associated with pregnancy or childbirth, such as lactation or the physical changes in the body that accompany pregnancy.

CAST BONDAGE: Bondage using plaster casts or plaster tape to immobilize a person.

CAT: Colloquial; from cat o' nine tails: A generic term for any flogger whose lashes are braided or knotted, regardless of the number of lashes. Commentary: Knotting or braiding the lashes makes the flogger considerably more painful.

CAT O' NINE TAILS: A specific type of flogger consisting of a handle, often made of wood and wrapped with cloth, with nine lashes affixed to it. The lashes are usually made of rope or of leather cords, and are braided or knotted. Generally more painful than many other types of floggers. The cat o' nine tails was commonly used aboard British Navy sailing ships beginning in the 17th century. Commentary: The original cat o' nine tails was made by unbraiding a section of the rope used aboard British sailing ships. Each rope was made of three sections twisted together, each section of which consisted of three cords twisted together, so the rope when untwisted had nine tails.

COLLAR: An item worn around the neck, sometimes equipped with a locking device to prevent its removal, and often worn as a symbol of submission. Also, verb To put a collar on, often as part of a ceremony indicating a committed relationship between a dominant and a submissive. See also corset collar, drop collar, posture collar, training collar, wolf collar; see related collaring ceremony. Commentary: Some people outside the BDSM community associate collars with animals or pets, and erroneously believe that a collar is a sign of humiliation or is used to dehumanize a submissive; however, the symbolic value of a collar within the BDSM community is completely different.

COLLARED: The condition of having engaged in a committed, long-term relationship to a dominant, often by means of a collaring ceremony of some kind.

COLLARING CEREMONY: A formal ceremony celebrating or symbolizing a commitment between a dominant and a submissive, typically during which a collar is placed around the submissive's neck. Commentary: There is no single type of collaring ceremony, and not all people in committed relationships in the BDSM community practice collaring ceremonies. A collaring ceremony in the BDSM community has many of the same kinds of social significance as something like a marriage or a wedding; often, the process of collaring is used to indicate a committed long-term relationship, particularly in TPE relationships. A submissive who has participated in such a ceremony is often said to be "collared to" his or her dominant. A collar in this context has symbolic value not unlike that of, say, a wedding ring. Collaring ceremonies may be public or private, and may include whatever elements the people involved find appropriate. Collaring ceremonies may or may not imply a monogamous relationship; one dominant may have more than one collared submissive, but it is extremely uncommon for one submissive to be collared to more than one dominant. A collaring ceremony is sometimes used to mark the formal beginning of a TPE relationship.

CONSENT: Affirmative permission, assent, or approval. In a BDSM context, "consent" is an affirmative assent to engage in a particular activity, freely given without coercion or distress. Informed consent: Consent freely given with full and prior knowledge of the conditions and potential consequences of the assent. Also, verb To give affirmative permission to engage in an activity. Commentary: Consent is one of the hallmarks of BDSM, distinguishing it from abusive activities which may appear superficially similar. Consent is based on the active, willing participation of everyone involved in a particular activity; for example, if two people are engaged in something like pain play, a key defining characteristic which differentiates this play from physical abuse is that all the people involved know exactly what they're doing, want to be there, and give specific assent to the activities in question, whereas the victim of abuse does not specifically and affirmatively assent to the abuse. Consent is valid and meaningful only if it is informed, meaning that all the participants have full knowledge of the activities to which they are consenting (including but not limited to the circumstances under which the activity will take place and the possible risks, if any, inherent in the activity); if it is uncoerced, meaning that the participants give the consent freely without threat, force, or intimidation; and if the people involved give that consent from a condition of sound mind, meaning their judgement in not impaired by drugs, disease, or any other condition which might cloud or distort their ability to make reasonable, rational decisions.

CONSENSUAL NON-CONSENT: Any situation in which one person knowingly and voluntarily gives up the ability to prevent another person from doing whatever he or she wants; as, for example, deliberately engaging in activities which the submissive may be physically prevented from resisting and does not have a safe word. Some forms of rape play are consensual non-consent. Commentary: Consensual non-consent is still consent. A person who gives consent in this way is giving affirmative assent to engage in an activity that he or she will not be able to stop in the middle; it can be thought of as consenting to an activity in such a way that the consent may not be revoked.

CONTRACT: A mutually negotiated, written agreement between a dominant and a submissive, outlining the submissive's limits, the activities the participants wish to explore, and the like. Commentary: BDSM contracts are not legally valid or enforceable, but are useful tools for defining what activities are and are not acceptable and in what contexts.

Usage: Used generically, not necessarily only to describe one's butt. Commentary: In some cases, repeated, prolonged, and very hard striking, as with a paddle or a crop, can create bruising deep enough that the area that is bruised becomes less sensitive. If this is done repeatedly over a period of time, this decrease in sensation can reportedly become permanent, resulting in leather butt. As the people I know tend to enjoy forms of play that do leave very deep bruises, and as I've never seen any cases of permanent reduction in sensation, I am of the opinion that such permanent reduction in sensation is probably rare.

LEG IRONS: A set of locking cuffs, often made of iron fastened together with rivets, with a length of chain about a foot long between them.

RISK AWARE CONSENSUAL KINK (RACK): A loosely defined code of conduct in the BDSM community which holds that a given activity is ethically acceptable between adults so long as everyone involved is aware of the risks involved, if any, and gives informed consent to that activity. The idea behind "risk aware consensual kink" is an acknowledgement of the fact that some BDSM activities may involve risk of injury, and that as long as all the participants are aware of any risk and consent to the activity, the activity is ethical. See related SSC, edge play (def. 1).

ROD: Archaic; see cane.

SAFE, SANE, AND CONSENSUAL (SSC): A code of conduct which holds that any activity between adults is acceptable as long as it is safe, sane, and consensual. Often held up as a test to whether or not a particular activity is ethical. See related RACK. Commentary: Many people see a flaw in the idea of "safe, sane, and consensual" because whether or not an activity is "safe" and "sane" is subjective, and because people may choose to engage in activities which might not always be "safe," as in some forms of edge play (def. 1). (This is true even outside the BDSM community; consider skydiving, for example). Because of this, SSC has given way to the code of conduct called "RACK" (risk-aware consensual kink) in some places.

SAFEWORD: A predefined "code word" which a submissive can use to stop an ongoing activity if it becomes too much. Commentary: Safewords are often used in situations such as resistance play, where the submissive may be expected to struggle or resist and where the word "no" might not actually mean no. In such cases, for safety's sake it's often helpful to have some word that does mean "no," and is a word unlikely to come up otherwise.

For people involved in service D/s, sexual submission may or may not be a part of the relationship.

Even something as simple as bringing the dominant a drink can be a token of the submissive's submission.

See related karada, shinju, kami, kotori, sukuranbo, takate-kote. Usage: Most technically, shibari is the act of tying, and kinbaku is artistic bondage. In general use, however, shibari and kinbaku are often used as synonyms.

VIOLET WAND: A device used for electrical play consisting of a handle, which contains a high-voltage coil called an "Oudin coil," and several interchangeable electrodes, most commonly made of glass and filled with a gas which glows a brilliant purple in the presence of an electrical field. Commentary: One of the most common and safest of electrical play devices, the violet wand works by creating a strong static electrical field on the electrode. The violet wand feels nothing like you might expect, and almost everyone I know, including people who believe they would hate anything related to electricity, wants one once they've felt it. Violet wands are often referred to as Tesla coils, though this is technically not quite accurate; an Oudin coil operates on similar principles, but the primary and secondary windings of an Oudin coil share a common core, while a Tesla coil is air cored.
