"Single White Female syndrome" is a colloquial term used to describe obsessive, manipulative, and potentially harmful behaviors, often associated with female relationships or interactions. The term originated from the 1992 film Single White Female, which depicted a woman (Hedra) who became obsessed with and eventually sought to replace her roommate (Allison). They are able to integrate into society and groups as nice and forthright while privately are raging. Their forte is beguilement.
