The basic plot was a high school sports coach was killing people in a smallish town. Guy was built like a football player with (I think) a glorious mustache. He was also banging some of the teachers and acting inappropriately with the students. Film had a lot of dark humor. 100% certain it was not any of the "Prom Night" movies. Any help?
