The douchepatch is the tinypatch of hair deliberately grown on the lower lip. It is basically a stupid, upside down mustache, worn only by douchebags, fratboys and Howie Mandel.
"Did you see Jen's new boyfriend?"
"Yeah, he totally had a douchepatch...WTF is she thinking?"
or
"Hey! That drunk asshole with the douchepatch just grabbed my tit!"
When numerous amounts of douchebags get together and ruin a perfectly good thing.
1 person who knows what he is doing walks into work with everything screwed up to the point of not being easily fixed due to the fact of a bunch of people who dont really know what they are doing but think they do. Person walks in and states "I do not want anything to do with this douchebachary!"
A compound insult, consisting of the insult Douchebag and the word Biter, thus referring to the person being insulted as someone who actually bites a vaginal douche. nuff said.
A person who you hate A LOT. Worse than calling them a douche bag. This person is majorly annoying and they have somehow pissed you off to the fullest extreme ever possible.
Kevin, my ex, is such a douche bitch! He seriously fucked my sister last weekend!
