The act of pounding and/or bashing a person's face into a wall or the pavement until their face turns to a gravy-like substance

the post-meal food drool in the corner of a person's mouth that they tastelessly leave for other's to gaze upon.
after we ate a the pizza parlor, Harry had facegravy all over his mouth and no one said anything, and we all enjoyed it.
