bunny boiler

The phrase "bunny boiler" is a slang term derived from the 1987 film "Fatal Attraction." It refers to a person, typically a woman, who becomes overly obsessed, possessive, or vengeful towards someone they are involved with romantically, particularly if the relationship has ended or if the person feels betrayed. It implies that the individual's behavior has escalated to the point of being dangerous or mentally unstable, like metaphorically boiling a pet rabbit as depicted in the film.
