Going into a store and stacking items in the middle of the aisle forming a tower. You then take a picture next to the tower with your hands in a point above your head.
dude we went towering this weekend and it was so much fun, we almost got kicked out of the store.
To climb a tower by any means possible, just for the sake of it, and for the adrenalin rush.
Fry: Hey Gonzalo!? Wanna climb that tall mofo, and smoke a joint at the top, listening to stairway to heaven, at four in the morning?
Gonzalo: Yeh dude, time for some TOWERING!
the act where you need two guys and oneguy or girl. One performs anal on him/her and he/she gives the other guy head, and the two guys high five in the middle, creating an eiffel tower look alike-ish.
Boone: I got eiffel towered last night!
Chanel #5: Me too! By two hot twins!
