pick the biggest guy in the room go up to him and just uppercut his ass ....or kick him in the nuts. They'll know not to mess with you . Worst you get is couple days suspension .

 Watch Back to the Future much?

Actually, havent seen it in at least a good 4-5 years, possibly more. I am Jack's randomness.

as was said above shrug it off for now, if it keeps hapening tell someone. Dont be scared of them, have confidence in yourself, I doubt these guys will do anything to you other than name calling.

Simple: Find the hottest chick in school, pay her $25 to hand around with you whilst you're around these peeps. They'll be jealous, and want to know how. Bullying solved.

btw - It would be much cheaper if the hot chick happens to be a relative - but make sure no one finds out about that, 'cause it could get a lot worse.

Stop wearing a fanny pack and lose the wizard trading cards... I Kid, I kid.

If you completely act like they're not there when they do this, they may lose interest. If you let it get to you, they will continue. Assholes like this pick on the weak, because it makes them feel powerful if they bring you down. If you don't let them accomplish their goal of bothering you, they may eventually just leave you alone.

LOL. That's just asking for being mocked if anyone finds out what you did.

Going at talkin to the teachers seems like a good idea, but most of them dont care, or their intervention would make it worse. Stay in Groups ignore them, and if you play some kind of sport in that gym class i dont know soccer, basketball whatever just waste them, teachem some respect.

Start a horrible rumour about how two of the guys who pick on you are actually gay together and they gave each other crabs. Then make fun of them for having crabs. God I am so fucking awesome.

Sorry to hear this, bullies suck.  But hey, you mentioned you go to Bx Science--well I went to Dewitt Clinton and Freshman Friday turned out to be bs.  As you probably already know, Clinton HS is much worse in terms of bullying/gangs etc.  I was scared to death of getting beat to a pulp on Freshman Friday as I was much quieter back then.  I begged my mom to let me stay  home on Freshman Friday but she would hear nothing of it.  In the end, it all turned out to be bull and nothing happened.  Just stay away from losers like that and if you can't (because you're in the same class) ignore them.  It defeats the purpose of anyone teasing you if you don't respond. 

However, if they ever get physical in their bullying then just walk over to my HS, hire a few thugs to do your bidding, and laugh at their black eyes the next day
