Brick Yourself

You say "Brick Yourself" when you suprise somebody and you want them to be still and shit scared of you because your robbing them. It came from the movie Menace To Society when the main guy Caine is robbin' a guys car while he's getting some fast food in the Drive Thru and he hops in the car and says "Brick Yourself Nigger" with a gun to the guys head before getting the guy to buy him some food and then steals the car.
