this is a sexual encounter in which the female is on top of the man (either riding or cowgirl) and the man is laying on his back and as she is bouncing on his penis, she rises too high and the penis slips out of the vagina and falls on the man's stomach, followed by the girl coming back down and flattening the penis against the stomach of the man.
Oh man my cock hurts so much today because the other day I got flapjacked by some heavy set broad.
