He's not the sharpest tool in the box, however he's trying hard to be in with the ''cool gang'' & is making a bigger tit of himself!
He surely doesn't behave like that in his normal life, he would have been called out on that kind of behaviour (or I'd like to think so).
As for the rest of his cronies, they're a bunch of immature morons, who are likely to continue with their obnoxious behaviour, because that's what has brought them ''fame'' in the past.
Sadly they're considered by some of the public as ''stars'', & therefore they can do no wrong, all of their behaviour is expected & applauded. A grim reflection of what fame actually means nowadays to some!
