Police are investigating a report that students from a New Jersey high school played a “Jews vs Nazis” drinking game.
A photo posted on Snapchat shows an apparent version of beer pong with plastic cups arranged in the shapes of a swastika and a Star of David.
Several young men are seen standing round the table with cans of Coors Light.
The image allegedly shows Princeton High School students playing “Holocaust Pong” or “Alcoholocaust”.
According to rules of the game posted online, the team of “Jews” receives an “Anne Frank” cup that they can hide anywhere in the room.
The team of “Nazis” has the ability to “Auschwitz” one of their opponents, forcing him to sit out.
Jamaica Ponder, a 17-year-old student who blogged about the photo, told NJ.com the students were her classmates.
Ms Ponder blogged: “Well, perhaps it is a joke. But then I guess the punchline would be: genocide. Pardon me if I don’t find that to be hilarious.”
She added: “They must be trapped in the delusional mindset that making a drinking game based off of the Holocaust is cool. Or funny.
“Or anything besides insane. Because that’s what this is: insanity. I’m not even Jewish and I’m still offended.”
The Princeton Police Department said on Friday it had started an investigation into the circumstances surrounding the photo.
Princeton Superintendent Steve Cochrane said he’s outraged that students played a drinking game with “clearly anti-Semitic” overtones.
