lust murderism (homicidophilia): the very rare condition in which a person is dependent on sadistic homicide of the partner, or the restaging of it in fantasy, in order to obtain erotic arousal and facilitate or achieve orgasm. Recorded cases are either heterosexual or homosexual, but not bisexual. The converse condition is the masochistic staging of one's own murder (autoassassinatophilia). See also serial killer.
