Ups and Jeans
Trendy un-cool guys out on the town who don't know how to dress well, so they wear an untucked button-up shirt, with jeans. Usually designer button-up shirts, and designer jeans just to "Dress it up." As in, wearing button-up shirts ALWAYS UNTUCKED, with Jeans.
What the hell are we doing in this bar? It's filled with Ups and Jeans! Ugghh.
