Warning: DO NOT get into the van with the blacked-out windows driven by the emo band. I don't care how sexy and cool you think they are, or how badly you want to make out with the lead singer you've been stalking. In reality, the emo band is merely trying to kiss the devil's butt by sacrificing a virgin (which, btw, you are so not) in an attempt to become rich and cool like Maroon 5.
Should you find yourself the unwitting victim of an opportunistic, devil-worshipping rock band, you will become a succubus. Neverending hunger will drive you to feast on the flesh of high school boys. Boys are, after all, easily led astray by their nether regions, making them the ideal victims. The only way to destroy your undead body is to drive a knife through your heart while you are weak from hunger, having been thwarted in an attempt to devour your bff's boyfriend.
This paranormal knowledge, and more, can be gleaned from viewing Jennifer's Body, the satirical horror film penned by Diablo Cody, the brilliant screenwriter of Juno. If you like a little funny with your scary and grotesque, you'll love this. Don't listen to reviewers who are boys. They are merely miffed at being portrayed as vulnerable chunks of demon food. (Boys, this is how girls have felt while watching slasher movies since the dawn of the horror film. That shoe's just on the other foot now.) The ending, in which said bff Needy (Amanda Seyfried, the perky blonde from Mamma Mia! and Dear John), gets revenge on the band who demonized (literally) Jennifer, is perfection.
Plus, there are great throwaway lines like, "Do you buy all your murder weapons at Home Depot? Gawd, you're so butch!"
