The Popcorn Man is the MTV Movie Awards mascot. This is a picture of the 2009 version. The only difference in the 2010 version is that his popcorn bucket head is yellow.
He is based on a short-story by Clive Barker. If you chant his name five times while looking in the mirror, he'll come out of the mirror with Virginia Madsen and kill you with a giant hook.
