Americans are known for their use of red and blue plastic cups at alcohol-infused student parties.
But the new "Jews vs Nazis" drinking-game - in which players create a swastika out of red cups and star of David out of blue cups - has caused an international uproar.
In a Fox4 interview, Rabbi Yitzchok Minkowicz of Chabad Lubavitch in south-west Florida, said the game was "a wake-up call" and called for more education.
Secondary school students at the Cape Coral High School in Florida posted a picture of the game on Twitter, with the caption: "This is what we play at parties."
The game involves players trying to throw ping-pong balls into the alcohol-filled cups of an opposing team. If a player succeeds, the opposing "Jewish" or "Aryan" team-player has to drink the cup into which the ball lands. The first team to drink all of its cups loses the game. "Jews" have an "Anne Frank” cup they can hide away, and the "Nazis" can call out "Auschwitz" to force a "Jewish" player to sit out of the game.
The image of the game seen here has been retweeted almost 2,000 times.
