What are good insults?!!?

There's this gir in my school who is a *****.. Everyone hates her and wants to beat her up. Me and my friends are gnna beat her up on the last day of school. Till then what are really good insults that will make her cry. Oh and about two months ago I got into a fist fite with her and I gave her bald spot cuz I ripped out her hair lol.
