What is that song from The Clique?

It's in the scene where Claire walks into the cafeteria,I think after
they make it look like she had her period.I haven't seen the movie in
forever,so I can't remember it at all,but I know it has something to
do with stuff like last years she wasn't cool and this year she is or
whatever.Right after that,I think,is when she meets her friend.Can't
think of her name.So,anybody know the song?I can't go back because now
it's DVD Only on Netflix.
