9. Fatty Spins “Doin’ Your Mom” (2009)

Nastiest lyric: Your mom’s the best, the super M.I.L.F./ Cause she loves to toss the salad even though she ain’t a chef.

Almost 18 million YouTube viewers can’t be wrong—or maybe they can. Ray William Johnson, leader of the insipid rap trio Fatty Spins, has what's claimed to be the most subscribed channel on YouTube, with over 5 million regular viewers. This is a truly stupid song with a deeply offensive title—but nowhere near as an offensive as these annoying raps.
