A competitor at the North American Grappling Association's Grappling Championship had a move in his arsenal that his opponent didn't see coming -- but he certainly smelt it. During a video that was shot at the event, one man submits in his match after his opponent apparently farts in his face. It's not exactly clear in the clip, but the victim appears to say, "He farted in my face. You farted in my face, man." He then vomits on the mat. A YouTube clip of the sneak attack is at just over 20,000 views and counting.
