I've read it on a few posts today. Don't ever be an asshole to someone for any reason, especially to get laid. If you are confident you don't have to be the asshole. You can be respectful, playful, and flirty without having to put down the person you are talking too. And, be honest, if you putting down and demeaning a woman makes her find you more attractive is that a turn on? To me it is the exact opposite, you are then just looking to get tail with a borderline broken woman.

While generally assholes have confidence, they are not what anyone should hope to become.
