What is not mentioned in this news story is 'The Circle Game.' Maybe the reporter never played this game as a teen or young adult. Maybe she never saw any of her friends play it. Maybe she is more familiar with the "Punch Buggy" (a/k/a "Slug Bug") game.

The cadets are obviously playing 'The Circle Game.' I know this because I am an expert on 'The Circle Game.' I played it for several years when I was the age of these cadets.

Proof is at the 32-second mark of the video when a cadet looks to his right, sees the circle, and quickly averts his eyes.

Later, at the 2:19 mark, you can see him trying to suppress a smile as he struggles to restrain himself from looking.
