The Rapper: Nyckz
The Fail: Everybody remembers the Internet meme that this rap battle created. During his verse, Nyckz dropped the memorable line, "Oh, you mad 'cause I'm styling' on you?" and it instantly took off. What you probably don't remember, though, is that Nyckz's opponent E-N-J responded to that line by punching Nyckz in the face to end the battle. That turned this into a fail on both sides.
