Douchepatch

The douchepatch is the tiny patch 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!"
