He jerks off at a concert and gets punched in the jaw

At a Korn concert, an audience member who was clearly a fan of System of a Down made himself conspicuous. At first, it looked like he was miming an imaginary drum kit, but in reality, he was behaving inappropriately. The surrounding audience didn't appreciate it, and one of the spectators punched him in the face. Security, then the police, intervened to remove him from the stand. The angry man was forcibly escorted out. It's hard to believe that he was completely sober during the scene.
