A rapper or MC whose music is largely comprised of "Uh!" over slow G-Funk beats. Very similar to a hipster, but less annoying, as they don't actually say any words.
My buddy recommended some music to me, but all it was four minutes of an uh'er moaning.
Boys who enjoy yaoi (a genre in Japan that contains sexual and/or romantic relations between two men); literally translates to "rotten boy"; corresponding female : fujoshi
