I know he can be annoying for many, but the way grown men effectively bully the kid is embarassing. Just have to ignore him and let him get on with it, he's a kid ffs
I'm 50/50 I'm not ever one for bullying and personally I just ignore him. But the kid does need to tone it down a bit and if a few chaps help him do that by taking piss a bit it might be better for him in the long run. Character building.
