We can't believe this actually happened! And while we're glad that the girl is alright, we can't believe someone didn't smack Afroman in the face for this!

The "Because I Got High" singer was performing in Biloxi, Mississippi last night, and during the show a young woman made her way to the stage and started dancing behind him. She wasn't doing anything to disrupt the set, but apparently Afroman was not a fan, because he hit her so hard she fell to the floor!

The stunned girl was able to get up on her feet, and it appears as though her boyfriend jumped on the stage just a few moments later. Afroman was later escorted off stage by police, who arrested him outside the venue for assault.

Seriously though -- what's wrong with him?! And why doesn't anyone in the crowd seem disturbed about this?!
