a sexual act that requires 3 people. 2 guys, one chick, and 1 other unfortunate soul. The chick bends over and one guy takes her from behind, while the other puts it in her mouth and then the two guys give a high ten, giving the illusion of the Eiffel Tower. The unfortunate soul is there to take the picture. No one will believe you if you dont have the proof.
