The butt luge is a complex but totally sweet way to take a shot. First you get a woman to lie down on her stomach naked, then one of you places your mouth between her legs looking at her butt. The person then pours a shot down the top of her butt and drinks it at the end.
Sick, did you see him last night!?" "Yeah dude, he did a butt luge to that ugly girl."
