Shagging(2001)

Shagging is a comedy following a single night of romantic chaos among eighteen-year-olds at a house party. When Alex breaks up with Isabel to pursue someone new, she retaliates by flirting with his best friend Schweiner—who's fixated on the aloof Sammy. Meanwhile, Sammy gravitates toward the perpetually stoned Sven. As the evening unfolds, the group navigates a tangle of unrequited crushes, jealousy, and heavy marijuana use. Desires shift, alliances crumble, and nobody quite gets what they want. It's a raucous snapshot of teenage romance and the messy aftermath of one unforgettable party.
