Can i have some insults to fire back at some retards who keep pestering me and my friends?

My friends and I(12 years old) are getting really annoyed at these 3 girls who are being so annoying.They say really stupid stuff and loads of other horrible things. we haven't told any adults yet because we think its to petty but today they started pulling my hair.I think they want a fight .anyway we have used up all our insults and comebacks.So i'm asking if you have any that we can use >>>thanks<<< (they are also ugly)
