Bodyweight kink
An informal and ambiguous search phrase that may refer to body-weight pressure, attraction to body size or physique, body worship, or weight-change fantasy; it is not one standardised kink term.
Drop
An informal umbrella for tiredness, low mood, irritability, disconnection or vulnerability that some people report after an intense scene or event. It may affect participants in any role, and many people do not experience it.
Hard and soft limits
Negotiation language for boundaries. A hard limit excludes something from the current agreement; a soft limit usually marks uncertainty, conditions or an area someone does not currently want to pursue without a separate discussion. Both remain the individual’s choice, and neither label makes repeated persuasion or surprise testing acceptable.
Play
Community shorthand for consensual adult kink, role-based or sensory activity. It can describe serious, emotionally meaningful or physically demanding experiences as well as light-hearted ones.
Scene
A community word with two common uses: a bounded period of negotiated kink activity, or the wider social world of events, groups and people associated with kink. Context determines which meaning is intended.
Sex-positive
An approach to sexual wellbeing that values accurate information, autonomy, consent, pleasure, respect and freedom from coercion, discrimination and violence. It can support many different choices, including choosing not to have sex.
SSC, RACK and the 4Cs
Community mnemonics used to prompt discussion about consent, risk, communication and care. SSC means Safe, Sane and Consensual; RACK means Risk-Aware Consensual Kink; the 4Cs framework proposes Caring, Communication, Consent and Caution. They are prompts for discussion, not certifications of competence, safety or legal permission for an activity.
Subspace and top space
Informal descriptions for changes in attention, emotion, self-awareness, time perception or absorption that some adults report during intense consensual BDSM experiences. The terms describe subjective experiences rather than recognised diagnoses. They do not establish consent, predict an outcome or explain away an unusual symptom that needs attention.
Vanilla
Informal, context-dependent shorthand for sexual or relationship interests perceived as conventional or not kink-focused. What counts as conventional varies between people, communities and cultures; vanilla is not a clinical category.
