Similar to "Butch Bitch" But usually in a position of power, ie manager or boss.
a typical masculine looking female manager 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 male employees.
Rob: Dude ask for the day off work
Rye No dude, the boss is a bitch
Rob: Are you assuming that she's a bitch based solely on that fact that she is butch?
Rye:(laughs) Yes, yes i am
Mike: So is it safe to assume that all butch bosses are bitches
Josh: Yes, yes it is, they are "Proper Butch Bitches"
