My first idea:

Prom Of The Dead/Prom Fright
(Cheesy titles, I know.)

This is a zombie flick that takes place on the most important night of every young adult's life: Prom Night. During the night's activities, a group of delinquents sneak out of the party in order to binge on a cocktail of drugs and sex in the nearby cemetery, away from the eyes of their teachers.

During this violent orgy, one of the teenagers knocks down a gravestone. Thinking they've gone to far, they decide to wander back to the party. What they didn't know was that they'd angered the dead. Coming back from beyond the grave, they make their way towards the Prom: hungry for flesh!

Sounds a lot like Night Of The Creeps to me
Except for the orgy...Teenagers don't really engage in orgies...They're usually still a bit in the 'insecure' stage at that age

Oh, and with slug-like things instead of graveyard inhabitants

Still the majority of the movie and end result would likely be extremely similar
