Or, Butch-Bitch relationship, is a relationship where one partner is domineering and the other just submits to whatever they say or do. Much like the caricature of a caveman dragging a woman by her hair to his cave, it's usually
characterized by a macho
guy who finds an intelligent, attractive woman, and by brute force takes
over her life.
It's more commonly used to describe lesbian
relationships, where the couple feels
the need to mimic this
typical heterosexual dynamic.
Harry Potter's aunt and her husband are a familiar butch-bitch relationship
. The husband flares
up anytime anything threatens the sanctity of his life, and the wife just looks withdrawn and frightened.
Also there's the stereotypical
where a petite, attractive "femme" will
date a woman in flannel and a mullet.
