School Spirit (1985)

The only thing keeping Billy Batson from the girl of his dreams is one little condom or rather the lack of one. Lucky Billy finds one at an all-night roadhouse but speeding back to his girl, he is killed in a head-on collision with a truck.

Now invisible, Billy must find his sweetheart and rekindle her fire but when he comes back to school as a ghost, his first stop is the girl's locker room, and he's beginning to "see" all the possibilities!
