A doucheberg is a guy (or sometimes girl) who seems like an awesome, thoughtful, sensitive person on the surface, but underneath they're a ginormous, iceberg-sized douchebag. You usually don't find out until it's too late.

A special kind of douchebag that resembles an iceberg in its douchiness.
Girl 1: I went out with Paul last night, what a gentlemen! I think I'll got out with him again.

Girl 2 (who knows Paul): Yeah, be warned, that's just the tip of the doucheberg...he's probably acting like that so you'll sleep with him.
