Depends on the show. The harder the show is, the less they will put up with that shit. If you go to a real hardcore show they won't allow fatties to crowdsurf. I deck people that shouldn't be crowdsurfing or do it too much. It's about being considerate to the rest of the crowd. If you aren't you'll get hit or at the very least I'll take your shoe off and toss it backstage where you'll never see it again.
