Get the FlapJackingmug. The sexual position involving two guys and a girl where the girl is held suspended in between the two men, tossed up into the air, and either one of the men try to catch the woman, in either hole, on his penis. Painful for everyone involved.

Get the Flapjackmug. The act of flipping a womans breast up, accompanied by the word "Flap!", then slapping the breast sideways while saying "Jack!".
