When over-masculine guys accuse other men of doing something like a girl, little kid, or a little girl, hence the name 'Bitch' Points. Often followed with a combination of punches to the chest by all men present that do not want to be accused of having Bitch Points themselves.
Guy 1: dude! i was just watching Hannah Montana! That chick is HOT!!
Guy 2: Wtf man? Even if she is, you get 20 Bitch Points (punches twice)
