I think it was his response to Rocky talking trash and trying to get him to stand and trade. Rocky kept making gestures like he wanted him to fight, and tried to push him around in the ring. I think Rocky said something to him at the end of the fight. Even the interview Rocky said MAB didn't come to fight tonight, he just smothered me every time I tried to hit him, he wouldn't trade with me, etc....

I think Rocky was frustrated cause he was beaten convincingly, and he was trying to goad MAB into exchanges.
