I dont think he was acting like a "thug" just being an idiot. Joey Porter was obviously instigating him into doing something but because Pacman is a mental midget he bit.
So, you are going to get offended by the use of thug but, use the term mental midget? Double standard much?
Btw... The hit that Burfict put on Brown could've ended his career if not paralyzed him. It also isn't the first time VB has done shit like this. When you look up the word thug in the dictionary Pacman's picture is there.
Do some research before you run your damn mouth.
