'The Last Exorcism' doesn't hit theaters until next Friday, but the horror flick is already scaring up a storm -- at least on the Internet.
Just ask a number of unsuspecting guys, who recently fell victim to a frightening viral campaign while browsing the video chat site, Chatroulette.
The lowdown: A pretty girl appears before camera and motions as though she's about to take off her top -- a dream scenario, we presume, for the guys watching on the other end. But that dream turns into a nightmare when the girl suddenly becomes possessed by the devil and lashes out at the camera. Check out their hilarious (and very NSFW) reactions after the jump.
