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 don't have the proof.
We are going to eiffel tower Sarah hardcore tonight!
