The Inbetweeners Movie (2011)
Movie
Released
The closest thing on screen to the exact feeling this list is for. Will, Simon, Jay and Neil finish sixth form, the British equivalent of senior year, and head straight for a guys' vacation in Crete, and the film understands that the fantasy of the post-exam trip is always better than the bad dancing, worse pickup lines and steady humiliation that actually happen.
It plays best with viewers who grew up on the E4 series, but the cringe comedy travels. On release it broke the opening-weekend record for a British comedy, so half the room has probably seen it already, and that only helps with the quoting.
