MGK wilds out at the mtvU Woodie Awards Festival.

Fresh off his appearance on XXL magazine's 2012 Freshmen cover, Diddy's newest "Bad Boy" MGK swung on over to Austin to bring his punk-rap swag to the mtvU Woodies Awards Festival stage. The Cleveland native and self-proclaimed reincarnation of Kurt Cobain (LOL) definitely brought his signature over-the-top energy and rapid-fire rhymes for an afternoon crowd of stoked kids at #SXSW, all eager to lend a hand on Kells' red boxers during his many stage dives.

If you've ever caught a MGK show before you know that the "Wild Boy" likes to get, well, wild. And I think getting almost completely naked onstage at the Woodies Awards Festival qualifies as officially "wildn' out." Speaking of getting undressed, MGK and his hype man clearly have some sort of rules regulating how much clothing the other is able to wear at certain times. I haven't figured out exactly how it all works yet, but I'm on it.

Do yourself a favor and check out Kells' performances of "Invincible," the Ester Dean-assisted hit and WrestleMania 28 theme song (why do I know that?), and "Wild Boy," the Waka Flocka Flame-featured banger that's been keeping folks in the suburbs locking their front doors and peeking out through the shades like in that "Trading Spouses" sketch from Chappelle's Show.

+ Watch MGK perform "Invincible" and "Wild Boy" below and after the jump, check out more Woodies Awards Festival performances, and tune in to the 2012 mtvU Woodie Awards airing Sunday, March 18, at 8 p.m. ET on MTV and mtvU.
