Italian school rebellion movie

Teenagers soaked in 60s nostalgia occupy a school in the 90s. There is a scene where the police is busing the kids and the kids yell obscenities at them. A guy gets some kissing action in library during the ''revolution'' and he talks about it to his buddies. The chick calls him immature and i think that's the end of their fliritng.

Come te nessuno mai

Thanks.
