I need super duper duper good comebacks, and help for bullying???!!!?

There are these girls that mostly bully me, they're pretty sporty and play basketball. I really can't remember the things they've been saying right now, but I need come backs that would work in almost every situation. NO CUSSING. I'll give some background info. I'm kinda popular, I'm a USMC girl, I get good grades, I don't have a boyfriend, pretty much all the teachers like me, I do good at sports (soccer mostly) I'm really not trying to brag! Sorry! I'm in the 6th grade. I never cuss. I am nice to almost everyone. I just need good comebacks. No Yo momma jokes, or old sayings that will just make them laugh. Sorry this was so long, and thanks in advance!!
