a typical masculine looking female with a profound butch haircut who seems commanding in every aspect of her life, she doesn't get fucked, she does the fucking and let's her girlfriend know that, can often be seen wearing a flannel with the sleeves cut off, and it is safely assumed just by looking at her that she is probably a bitch and doesn't take shit from anyone
Mike: Dude go in there and try to buy some alcohol
Josh: No dude, she looks like a bitch
Mike: Are you assuming that she's a bitch based solely on that fact that she is butch?
Josh:(laughs) Yes, yes i am
Mike: So is it safe to assume that all butch women are bitches
Josh: Yes, yes it is, they are "Butch Bitches"
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 The husband flares up anytime anything threatens the sanctity of his life, and the wife just looks withdrawn and frightened.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 lesbian relationship where a petite, attractive "femme" will date a woman in flannel and a mullet.
