We certainly hope that the hand symbol displayed by some students from the U.S. Naval and West Point military academies during the Army-Navy football game in Philadelphia on Saturday was nothing more than a juvenile gesture from the so-called "circle game," in which one person shows the symbol — a circle made with the thumb and forefinger — and another gets a punch in the arm when caught viewing it.

It's the kind of testosterone-friendly pastime you can imagine being popular among boys and young men in boot camp, a frat house or a high school hallway. The game, supposedly developed by some guy in Ohio, has roots going back to the 1980s and has been the topic of a Reddit discussion, an episode of "Malcolm in the Middle" and various online articles looking into its origin.
