Damn bro that kid sounds like a right little sh*t
I'm not condoning violence but sometimes it takes 'a quiet word' for things like this to settle down.
The next time you see him out wait until he goes to the toilet, follow him, grab his balls and tell him that if he doesn't leave off you'll rip them off and feed them to him:guns:
I had the same kind of problem when I was in school, at the age of around 13-14 I got a lot of sh*t from this one lad, so I just stood up in a science lesson and punched him in the face.
We started scrapping until the teacher broke it up, man I wanted to kill him.
I know this wasn't the best thing to do, but that kid sure as hell never bothered me again.
