This glossary of BDSM (an initialism for bondage, discipline, domination, submission, sadism, and masochism) terms defines terms commonly used in the BDSM community.
BDSM activities are described as play in BDSM terminology.
BDSM abbreviations have their origins in classified personal advertisements, where euphemisms for paraphilic and socially-disapproved practices were required by periodical editors to circumvent censorship and obscenity law.
The term BDSM is a portmanteau of initialisms intended to encompass all of the following activities:
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. Some extend this to honorifics and capitalization: for example Master Rob's slave, linda, may refer to him as Sir and herself as i (or as "this slave", restricted from referring to themselves in the first person). Others are highly dismissive of this "slashy speak".
- 24/7: A relationship in which protocols are in place continuously.
- Abrasion: Using something rough (such as sandpaper).
- Adult Baby/Diaper Lover (ABDL): Adult babies receive gratification from role-playing an infant (known as paraphilic infantilism, a form of ageplay). This can involve submission on the adult baby's part, often to a designated "caregiver", e.g. a daddy dom. Diaper lovers receive gratification from the wearing and often using of diapers. Whilst these two paraphilias are distinct, it is common that a person who enjoys one will also enjoy the other to some degree.
- 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.
- Auctioned off: Dominant auctions off the slave to the highest bidder (usually supervised and for temporary use).

- Edgeplay: SM play that involves a chance of harm, either physically or emotionally. Because the definition of edgeplay is subjective to the specific players (i.e., what is risky for one person may not be as risky for another), there is not a universal list of what is included in edgeplay. Examples may included bloodplay and gunplay.
- Enema play: Both women and men may experience sexual arousal from enemas finding them gratifying or sensual. Enemas are also used in sadomasochistic activities for erotic humiliation or for physical discomfort.
- Erotic humiliation: Humiliating someone during a sexual act. This act could be either verbal or physical for example, insulting a partner, making a partner display their private parts to a group of people, or even urinating or defecating on a partner. It can be a great source of pleasure for some people. There must be boundaries, safe words, and limits because without caution this play can destroy a relationship or a partner's self-esteem.
- 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.)

- Fisting: Inserting a hand into the vagina or rectum.
- Genitorture: Torture of the genitals.
- Golden showers: Urinating on, or being urinated on by, another person.
- 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-practitioners 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.

It can also refer to someone who has no interest in the activity – it "squicks them out" – but who has no prejudice against the play or people who participate. It is believed that the word is a combination of "squirm" and "icky" and is used to imply an uncomfortable feeling mixed with disgust. The term is used instead of disgust because that word implies moral repugnance to the act.
- 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.

The sub may feel disconnected from time, space, and/or their body, and may have limited ability to communicate. It is critical that a Dom/top take responsibility for the sub/bottom and be aware of their sub's well-being if they are in subspace. Long-term dominance and submission relationships without impact play may alternatively define subspace as 'a mental state where the submissive feels a deep emotional resonance or connection with the dom'.

Old Guard now usually refers to high protocol groups, particularly gay leather BDSM groups; people who use this phrase may be romanticizing a perception of leather history: see Old Guard leather.
