- n. Literally, the love of asphyxia. A sexual practice, generally not terminal (and even then probably only accidentally), of arranging to produce asphyxia at the moment of orgasm. The practice may have originated from the observation, described in a novel by the Marquis de Sade, that hanged males sometimes achieve erection and even ejaculation before dying.
From asphyxia + -philia (Wiktionary)
