Dungeon
In BDSM usage, a room or venue equipped for scenes, with furniture such as crosses, benches and tables and its own house rules; also used for parties held there.
In kink usage a dungeon is a space set up for scenes. Wikipedia’s Glossary of BDSM defines it simply as a space fitted out with BDSM gear where scenes can take place. The Portland Leather Alliance’s newcomer guide uses “dungeon party” as another name for a play party and says the venue provides the large furniture, such as crosses, benches and slings, while guests bring their own portable gear. Its house rules for the dungeon ask players to disinfect equipment after a scene, ban recording devices including phones, and place the space under dungeon monitors whose decisions are final. Rules differ from venue to venue, so the guide tells newcomers to read each event’s own rules before entering.
