Knocking on the door of an unsuspecting victim and not running away.The objective is to see how long you can get the person to have their door open for.
Essentially the opposite of nicky nicky nine doors.
Popularized by Neg Dupree of the British TV show, Balls of Steel.
Fun for the whole family!

Guy 2: I played "knock and don't run" and got a stiff hook to the jaw.
Guy 1: You are such a BAMF.
