The fight raged on for over a half-hour, reported ABC News. From the Huffington Post:
Witnesses said it was a frightening experience, with people running through the halls,screaming and banging on doors, the Daily Breeze reports. The frenzy, one witness said, was fueled by a combination of liquor, testosterone and girls.
And of course, there was some Sean Michaels-style clothing removal.
Some frat members took off their dress shirts to join the fight, and others had their formal attire ripped off in the chaos.
Cell phone video of the fight, which somehow managed to involve no arrests, is below.
