Spirit week at a Utah high school was marred this year by Holocaust jokes on social media and a dodgeball team named “Ballocaust,” Good 4 Utah reported on Friday.

A concerned parent reportedly contacted Good 4 Utah with a complaint: “Those kids were able to wear those shirts on the court at a school-sponsored activity. Their name was announced over the PA address system with many students present at that school-sponsored activity. Someone should have put a stop to it.”

According to the report, the parent revealed tweets featuring pictures of Adolf Hitler celebrating the “Ballocaust,” and another tweet in which the user replied, “Your team about to fall harder than Anne Frank.”

Some users posted enthusiastically once the story of the “Ballocaust” team was picked up by the news.

Anyone wanna come over and watch the “ballocaust” story @ 10 with me? They may not of won but they on the news?

“I find it very disturbing that we can make a mockery, in today’s day and age, that we make a mockery of an event where millions of people lost their lives,” the parent of a student at Tooele High School said.

Principal Jeff Hamm did not return Good 4 Utah‘s call about disciplinary action.
