Afroman, real name Joseph Edgar Foreman, rose to fame with his 2000 Grammy-nominated pro-marijuana song "Because I Got High." He was in the middle of a concert when an unidentified woman walked onto the stage behind him. She began dancing near Afroman, who suddenly turned around and delivered a devastating right hook to the woman's head, knocking her to the ground. Afroman then continued performing as if it was no big deal.
Cops eventually stopped the show and escorted Afroman off the stage. A rep for Afroman told TMZ that the rapper didn't know whether the victim was a man or a woman, he merely reacted to someone being on the stage and defended himself.
