In the first part he's definitely saying something, and I'm going to have to agree that I hear "what's wrong with you" actually more specifically I hear "what's wrong wit chu" You must have been listening really hard to hear that I would have never realized it before but now that's all I hear! lol. I don't really think it's a message or anything, there's so much being said and going on in the background that I think it was just put in there.
