During a 2 girl 3some, the guy lays on his back and one girl rides his cock while the other rides his face, the girls are facing each other and high-five. Similar to an Eiffel Tower, but with a different gender distribution.
"I had a 3some with 2 ladies last night and at one point they high-fived to form an Eiffel Triangle."
