An adjective or abstract codeword used privately in the chemsex & more specifically urination/defecation fetishism community around 2015/16. Originally a codeword to permit entry into specific darkrooms, private events or hotel rooms in London, it would indicate the participants understanding of the nature of those group events (versus more common Greek style 'orgies'). Though this term is not used in the current scene; gay or transexual (male) ex-participants have moved this word in their vocabulary to indicate excitement or excess.
