A School movie that is Bully the videogame but with Girls and a goth chick, named Burguer and Berry Something

Movie From the 2000s probablly from England
The movie’s plot basically is about a nerdy girl that studies at a very rigid School and ends up meeting this kinda goth girl with this rebel attitude and short half dyed and black hair, that lives at her mom’s house and the nerdy girl ends getting kicked out of her school, moves to her goth friend’s house and changes to her friend’s public caothic school.
I remember that the movie gives of the bully the videogame vibes so much, in the school there’re very specific different groups or tribes of students, and her friend is part of one of them that is the ‘‘Cool rebel kinda goth rock’n roll chicks(?)’’.
They are at Middle School then the nerdy chick becomes one of them, changes her appareance and start hooking up with all the highschool older dudes and she become rude and cocky as fuck, to the point that her goth friend don’t bare her anymore, near the end of the movie there’s this scene that the ‘‘Cool goth chick’’ group goes to a party, use drugs and make a circle around a guy and everyone of them sucks the guy’s cock.
About the tittle, is a mixture of ‘‘Burguer’’ And ‘‘Berry’’ something.
