A whiskey mustache is when a naked woman straddles or sits on your face while she pours a shot of whiskey between her tits all the way down into your mouth. IMPORTANT: Please practice this move with water first. Delicious whiskey in your eyes is very painful and it is a shame to waste a perfect shot of whiskey.
Hey good looking. I sure am thirsty. Why don't you get buckass naked and give me one of those whiskey mustaches.
