I've always found that historical costumes work wonders. Louis the XIV always pulls bull rider level ass.
You could dress up as a bull rider, and if a girl asks you if that's your costume, you tell her, "**** no. I'm a bull rider for reals. Costumes are for pussies that live sad, insignificant lives who are too gutless to get on the back of a 3,000 lb. animal that wants to stomp your guts out." Laid for sure.
