MTV Movie Awards Craziest Moments: From Aubrey Plaza To Rebel Wilson's Nip 'Slip'

Jamie Foxx and Samuel L. Jackson took the Best WTF Moment Award, but plenty other moments made us say, 'What the?' on Sunday night.

Whew! OK — now that was a crazy night, wasn't it?

Three Golden Popcorns for Earth's mightiest heroes and a whole bunch of other victories later, and the MTV Movie Awards are once again in the pages of history. The 2013 edition of the show was hosted by "Bridesmaids" and "Pitch Perfect" breakout star Rebel Wilson — who, fittingly enough, took home the night's Breakthrough Performance award — and as one could guess based on Wilson's previous work, it was a pretty wild ride, filled with awkward vagina jokes and glorious stage-crashing.

Relive the night's craziest moments in the video above, and keep on reading for our own five favorite crazy moments of the 2013 MTV Movie Awards.

5. Rebel Wilson's Nip Slip

The Movie Awards host took it upon herself to use her new platform as a place to speak about body image issues. We just had no idea her body image issues involved a third nipple — and we certainly had no idea she would flash said nipple in front of the entire world.

4. Taylor Lautner Got Fat

And he couldn't take the weight off in time to accept his Best Shirtless Performance award, which he earned for his famous abs as Jacob Black in "Breaking Dawn." We always feared what would happen to the "Twilight" stars once the franchise came to an end, but we never expected Lautner would let himself go this far.

3. The Iron Man(gina)

As every actor in Hollywood keeps getting sucked into the superhero game, it was only a matter of time before Rebel Wilson got involved as well. But who would have guessed that she would fit so perfectly inside the Iron Man armor — or, as it's technically called, the Iron Mangina? Apparently, James Franco had a hunch, and it paid off!

2. The Unlocking

What, you missed that part of the show where Seth Rogen dropped trou and revealed his conservatively manicured pubic hair, then proceeded to use a massive key to unlock Danny McBride's chastity belt? You better go watch the show again!

No, it wasn't rehearsed. Yes, it was super-awkward. But it was also super-crazy, and sometimes, super-crazy is super-fun to watch.
