How to get a jerk to fight me?

So, there's this jerk who won't leave me alone. Whenever he's with his group of lackeys who worship him, they look at me and laugh- I can tell that they're making fun of me, and they've even made fun of me to my face before. In reality, he's a weak little ***** who can't do anything except keep up his gay popular image by putting other people down. I'm not a violent person, but I've had enough of his crap and I want to put a stop to it. I've tried being nice, being firm, and telling him to **** off, but he just won't leave me alone. As I said before, I'm not a really violent person, and I've never really gotten into a high school fight before. I know that I can kick his ***, but how do I challenge him to a fight if he's always with his retard friends, and how do I beat him if I fight him? Pls help!
