When you are giving it to your girlfriend doggy style, then secretly switch with your buddy waiting behind you, walk out of the house, then creep in through the window where she can see. (may require temporary blindfolding.)
The bitch cheated on me, so me and Tony gave her the St. Louis Switcheroo.
