Firstly Mean Girls is not number 1. It's not even top 5 makes me think this writer was clearly 15 in 2009 and has no concept of the quality of 00s Teen Movies.

A list of quality (and so bad they are good) teen movies not on Buzzfeed's Definitive Ranking of 00s Teen Movies:

Slap her, She's French

Saved!

Get Over It

Not Another Teen Movie

High School Musical

Final Destination

Road Trip

Love Don't Cost a Thing

Eurotrip

It's a Boy Girl Thing

Superbad.
