We effed up and we know it. Complex's countdown of The 25 Best Movies of 2010 tragically omitted last year's most entertaining joyride, Piranha 3D. Alexandre Aja's tongue-in-cheek remake of producer Roger Corman's 1978 vicious fish classic significantly upped the ante and delivered all the gratuitous nudity, gore, and laughs that a person could want. Shame on us, seriously. It's too late to rectify things with the 2010 countdown, but not too late to team up with Sony Pictures Home Entertainment to give away five copies of Piranha on DVD and spread the fun! To win your copy, tweet at Complex using the hashtag #piranhadvd and tell us why YOU should be one of the lucky five recipients. Tell us what your favorite scene is, how Piranha 3D helped you get laid, or just how damn broke you are. Whatever. Get creative to convince us and you'll have a new DVD to sink your teeth into.
