Term of outrage commonly used by large, angry, black women to express their disbelief at being insulted.
In a KFC, after ordering the family bucket of chicken a rotund black woman was asked, "Do you want this for here or to go?" She angrily replied, "B'scuse me, muthafucka! You think I'm gon' eat all this damn chicken myself?!" To which the cashier quickly said, "Shut up bitch, I don't know yo life!"
