biastophilia

Definition

Paraphilia of the sacrificial/expiatory type in which sexuoerotic arousal and facilitation of orgasm are dependent on the surprise attack and continued violent assault on a non-consenting, terrified, and struggling stranger. Biastophilia may be either heterosexual or homosexual, but is predominantly the former whether the biastophile (assaulter) is male or female. Acquiescence on the part of the victim may cause the biastophile to lose interest or, more often, to increase the threats and violence.
Etymology: From the Greek, biastes , rape or forced violation, and philia , attraction to.
Synonym: raptophilia.
