An activity for kids who go to underground shows, it involves crowdsurfing your way to the stage and then jumping back into the crowd. If the stage is small enough, a stage diver might just get up on stage and dive off into the crowd. At some shows, particularly hardcore/metalcore tough-guycore shows, the stage diver will jump into the crowd feet first, kicking, and punching violently because he is stupid and has no respect. The crowd generally does not like stage divers who can't see their feet. This activity is not usually found at larger concerts for the venues like to put up barriers between the stage and the floor.
