What a mean
mean man

Girl was just doing what millions of other girls have done at concerts when they're happy and groovin' to the music, along with the musicians. Sure, maybe she should have been personally invited up on stage and if he was uncomfortable with that, just politely but firmly ask her to get off, or have security do it. But to slug her with such force?! He is the Patron Saint of Concert Cunts! Hope his career is over
