Someone who at first meeting shows a little bit of their douche self, but on getting to know them better, the full extent of their doucheness becomes apparent. (Likened to the iceberg that only shows a small fraction of its total size)
Upon seeing a known douchebag coming at him he said in his bestcaptain's voice, "Doucheberg straight ahead!"
1. When somebody seems like a douche at first, but then is proven to be an even bigger douche than expected
2. Someone who hides 90% of their douchiness under their exterior
3. A jewish douche
1. Dude, he's such a doucheberg. I knew he was a douche, but I didn't think he was this bad!
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.
