I'm An Arsehole

A few months back, a friend told me that although she liked me, not many people do. I laughed and told her she's right: I'm a bit of a dick. My quiet demeanour has me lumped with the "nice guys" but I've got habits that don't endear me to people. Getting to the point, after a potluck bbq Thursday night, and one too many glasses of wine, I dreamt that I let my inner douchebag shone through. But I disguised my dickish-ness as clever jokes and witty insults. People responded positively and thought I was hilarious. Now, would this work in the real world?
