While the MTV Movie Awards are all about celebrating the best from the past year in film, they're also about shining a light on the very worst. This year, we're introducing a brand-new category for all the deliciously despicable characters: Best On-Screen Dirtbag.

We've broken down all the nominees in the category below, but it's up to you to vote one member of this detestable quintet to the podium to collect his or her Golden Popcorn. We will all find out who the worst of the worst is this Sunday, June 3, at 9 p.m. ET live on MTV.

Bryce Dallas Howard - "The Help" If an on-screen dirtbag does his or her job properly, naturally the audience will beg for some comeuppance. Without a doubt, none of this year's love-to-hate-'em nominees got it worse than Bryce Dallas Howard's horribly racist Miss Hilly. Apparently, revenge is a dish best served in the form of a chocolate pie made out of human feces.

Colin Farrell - "Horrible Bosses" Even if it weren't for the cocaine addiction and his propensity for firing those that "creep him out," Colin Farrell's character in last summer's hit comedy "Horrible Bosses" may have ended up on the short list for On-Screen Dirtbag for that comb-over alone. Sometimes a poor choice of hairstyle can be just as bad as a person's behavior.

Jennifer Aniston - "Horrible Bosses" There's nothing wrong with a small workplace crush as long as human resources has been notified, you keep your conversations work-appropriate, and you don't spray your co-worker's pants with water in order to see the outline of his junk. Jennifer Aniston's character in "Horrible Bosses" did not heed any of these rules as she aggressively tried to seduce her dental hygienist, played by Charlie Day.

Jon Hamm - "Bridesmaids" Sure, he might seem like a great guy. He's rich, and hell, he looks like Jon Hamm, but Ted is not a man you want to be around. He does that thing that can only be described by Kristen Wiig as she drags that back of her limp hand across her face. It's not pretty.

Oliver Cooper - "Project X" Sometimes dirtbags are funny. One of our nominees this year, Oliver Cooper of "Project X," has the distinct honor of earning nominations for both Best Comedic Performance and Best On-Screen Dirtbag. And that's the beautiful balance that Costa strikes. Yes, he's going to turn up the speed on the treadmill that you're running on, but you'll probably laugh about it later.
