28 Movies to Watch When You're in a "Mean Girls" Mood

"Booksmart" is another irreverent high school comedy, this time about two teens who realize just before graduation that they could have — and maybe should have — been partying this whole time. They're intent on having the best night of their lives before getting their diplomas. Their one night of partying takes them on something like a magical mystery tour of their high school and their classmates, and as they both pursue the love they worry they've been missing, they also solidify their friendship even more.
