A Slice of Terror (2004)

Pizza isn't the only thing delivered in this horror-comedy. Zaffo is a pizza-delivery guy who's constantly ridiculed by his friends and co-workers. When a group of teenagers force Zaffo into a homoerotic situation, he finally decides to fight back, enlisting the help of a psychic and an over-the-top gay customer to cast spells on the boys. Once Zaffo has them under his power, he tortures them … one at a time.
