This person's original name is Charles, but he tends to get mad easily and turn into a Hulk. So the word Chulk is born, he has a habit of pulling two hockey sticks out of his pants and starts to chase you when he is mad. He will then poke you with a hockey stick when you are on the ground and forces you to say that your sorry.
Oh for fucks sake, this motherfucker turns into Chulk AGAIN..... It's the forth time this week!
