douchebag

A guy who has no brain, acts like he's part of the jersey shore when he really isn't. Tends to be a dick to everyone who isn't his but buddy. An overall asshole in all aspects

Ronnie, pauly d, the jock in your school.
Guy: "dude stop being such a douchebag"
Douchebag: "I'm not a douchebag you're all just faggots"
