What’s the best comeback for when someone makes fun of you

I go to school in year 12 and I constantly have year 7 kids make fun of my Mohawk. (Australians know the ones. The ones with rat tails and wear tn’s and tech fleeces.) but I really want something quick to throw at them or even just catch them off guard. I’m not going to lay my hands in them because it was already enough of a fight with my PUBLIC school to let me where my Mohawk up. Right now I just ignore it but having something quick to throw at them would be funny. I always hear them saying the n word and f slur “as a joke” so i seriously wouldn’t feel bad with anything. Any suggestions or should I just stay quiet.
