Friend driving me up the wall...

My friend is driving me up the wall.
He annoys me;the whole class.
He is bossy and arrogantand sometimes (although I do not like to use the word)asshole and a jackass.
He is a root of the class problems and he spreads rumors that is why I hate him.
Sometimes... I feel like breaking all his bones and wish he was handicapped. Or just change school. If that happens, we will have a party.

Wish can give some comments or opinions on what I should do... ...
