It's the end of June which means for most people, school's out! While your OP hasn't been in an educational institution in over a decade, I still think it's fun to get into the summer mood with some end of school year hijinks on film. Let's start!

Set in 1993, Aubrey Plaza stars as overachiever Brandy Clark. After getting drunk at a graduation party and experiencing horniness for the first time, Brandy realizes she isn't as sexually experienced as her peers. Worried that she'll enter university without sexual know how, Brandy develops a plan to have a variety of sexual experiences over the summer culminating in losing her virginity to local hottie, Rusty Waters (Scott Porter aka Jason Street from Friday Night Lights). This is a hilarious sex positive movie and Bill Hader's role as the stoner pool manager is greatly under appreciated.

This isn't really an end of school movie but it has all the sex, drugs, and shenanigans you'd expect from a movie starring the Ramones. Set in 1980, this b movie stars PJ Soles (the best friend/sidekick character from Carrie and Halloween) as Riff Randell. Riff is a terrible student whose disciplinary record takes up an entire filing cabinet. She is desperate to meet The Ramones and give them a song she wrote (titled Rock n' Roll High School, obvs) but when the school principal rips up her ticket, she must devise another way to meet the band.
