He's just an asshole. He's a smug arrogant unwarranted little prick who only talks and acts the way he does because nobody knows where to find him.
It would be worth the weekend in jail and 3 months of probation to knock him the fuck out. That's always the funniest thing ever when someone who doesn't realize that there's nothing keeping you from hitting them in the face gets hit. The wide-eyed look of shock of "oh no I'm not behind my computer. Life is not a video game and I can't change the channel on this. I'm getting my ass kicked"
