(chur pee) The act of repeatedly attempting to play-pinch someone on the backside. Especially when the pinchee is trying to escape up a flight of stairs. Usually performed by couples in a play-fight situation as a form of foreplay.
I reached to top of the stairs and fell on the bed laughing as Todd finally managed to churpie my left butt cheek.
