Forget Best Sound Mixing — the MTV Movie Awards are all about the categories that really matter, like Best Kiss, Best Shirtless Performance and, of course, Best WTF Moment. And it's the latter that we're focusing on today in anticipation of the big show, starring Rebel Wilson as host and airing Sunday, April 14 at 9 p.m. ET.

From projectile puking to simulated sex that definitely deserves a clean-up on aisle 9, five squeal-worthy scenes are up for Best WTF Moment at this year's MTV Movie Awards.

Take a closer look (if you dare):

Anna Camp, "Pitch Perfect"
Aca-awkward! As co-head of the Barden Bellas, Aubrey (Anna Camp) leads with an iron fist ... and a weak stomach. Her nerves get the best of her, not once but twice, leading to the most spectacular display of vomiting we've ever seen. (And Hana Mae Lee's barf angel only ups the ick ante!)

Denzel Washington, "Flight"
If we've learned anything from the movies, it's that Denzel Washington can commandeer any form of mass transportation handily. Yet, his inverted landing in "Flight" is still something to behold — and make you want to buckle up tight.

Jamie Foxx and Samuel L. Jackson "Django Unchained"
The "D" may be silent, but we wouldn't be surprised if it stood for "deadly." In the closing moments of Quentin Tarantino's blood-bathed Western, former slave Django (Jamie Foxx) gets his ultimate revenge, blowing up Calvin Candie's (Leonardo DiCaprio) estate in spectacular fashion, with servant Stephen (Samuel L. Jackson) tucked not-so-safely inside.

Javier Bardem, "Skyfall"
Sure, as Bond villain Silva, Javier Bardem is slick, suave and sorta sexy — but that's only until he removes his orthodontia. Much of Silva's face was eaten away in a botched suicide attempt, leaving him a severely broken man, both physically and emotionally.

Seth MacFarlane, "Ted"
Ted clearly never took a workplace sexual-harassment seminar. When he spies the woman of his dreams ringing up groceries a few check stands away, the bear whips out his best moves, which include something called a "Dirty Fozzie." We'll just let you watch that one.
