Beyotch!

My daughter seems to think this is a good name for me. As I calmly tell her to let go of her little brother's head, she tells me in her most authoritative voice, "no you beyotch!". I promptly get off my fat behind to reprimand her. I tell her that good little girls do not call their mommy and daddy names. To which she replies, "no beyotch". What do I do????
