Partying is like the beach and sex: everyone likes it so there is no need to talk about how much you like it. Resist the urge to show the world that you are a beer pong master or keg stand king. You are looking for casual sex with strangers; odds are you are a pretty outgoing guy. So, there is no need to demonstrate your red solo cup credentials. Yes, you're going to fuck, but there's a chance the lady would like to have something resembling intelligent conversation before, during, or after. Most women expect to talk about something other than Edward Forty-Hands post-coitus, so see if you can't muster up just an ounce of class in those profile pics.
