A Dickading
When a guy acts like a total idiot, thinks he's the best at everything, flirts with every girl, drinks too much, and can't commit to anything or anyone. Usually happens in your 20s.
He broke up with three girls in one week and still thinks he's the best looking guy in the world.
He drinks all night, shows up to work hungover, and still thinks he's the king of the office.
He says he's going to get married next year, but he's still sleeping with his ex.
