CM Punk and Chris Brown have been sparring over Twitter, and it has now become a nasty war of words.

Earlier this week, Brown accused Punk of taking steroids and having defective “man junk”, and last night Punk replied with the following video response he posted on his Twitter page where he reaffirms his straightedge lifestyle, rips into Brown for his mistreatment of women, and challenges Brown to a fight where the proceeds go to a women’s shelter of Punk’s choosing:

Also in the video, Punk calls Brown less than a man, says he wants to choke him out (in the ring presumably) and calls out Brown for having to have an entourage to do his handling.

CB’s Slant: Think Brown picked the wrong person to mess with? Two words: Pipe Bomb.
