Why is he such a douche to me?

At my school there is this kid Jaden and thinks he's all cool because he smokes and walks like a gangster. He will absolutely anything to annoy me, and it's getting on my nerves. For example, me and a few of my friends are makinga saw spoof video for youtube. One day, we were rehearsing and he snuck up to me, punched me in the face, took the script, and gave it to my neighbors who I hate very much. He is always a mother fuckur to me and I hate it. If I tell the principal, he will make up some story that makes me get in trouble and him off the hook. We are all 10, and HE SMOKES!! Thats ffuucckkeedd up. How can I cope with this assss hole?
