So when there's a line a couple dozen deep in between sets at a show it definitely isn't the appropriate time to jump in the bathroom with some dude and blow him. I know you're a horny shit but could you wait until the bands start up again and there isn't such a need for urgency? It may be a tad more discreet as well. Also, if you really gotta do that wiping your mouth as you leave makes you look even trashier than I thought possible. Use the toilet paper and a bit of water. Or just take a piss and blow someone after the show or in an alleyway instead. You'd be less of a douche.
