Youth sports is all about kids learning the fundamentals, teamwork and parents or coaches fighting.

This third grade AAU coach not only lost the game, he lost is damn mind!

After the teams start to exit the court, he makes his way over to the bleachers and proceeds to beat the crap out of a man in the stands.

We don't know what was said before the incident, but we do know that the coach was arrested for assault.
