Dodgeball is a fine American tradition. The game is simple, throw the ball, avoid the ball; it doesn't require any fancy plays, complicated strategy or anything else. This teenager doesn't know that yet.
I'm not saying this move (at about :40 in) isn't awesome, it's totally rad looking, but it is also totally unnecessary.
Had he been doing the move to avoid a ball, that'd be one thing, but he was just doing it to show off. (And while yes, he does avoid a ball coming his way by doing this, that is a happy coincidence, he was doing the move to impress everyone and it just so happened a ball missed him in the process.)
