Gymnasts Butt Heads During Routine, Makes Sickening Sound [VIDEO]

Watch as two gymnasts attempt to pull-off some sort of routine where they both flip into the air, really close to each other, but come way too close this time.

Listen to the TERRIBLE sound as the two gymnasts butt heads mid-air. We hope both were able to walk way from this, but by the sound of it, I bet they both had a massive headache after this terrible incident.
