The question is related to the "Air Ball" Phenomenon, which was studied by Cherrill P. Heaton starting in 1990 and published in 1992 as "Air Ball: Spontaneous Large Group Precision Chanting." Heaton observed that at basketball games, when a player aims for the basket but misses entirely, the crowd will chant "Air Ball" in perfect unison on the notes F and D.
It sounds like a joke, and Dave Barry mentioned it in a humor column, but observers find that it continues to hold up. Heaton himself attended dozens of basketball games with a pitch pipe, and also studied video tapes of professional games.
When you say "Uh oh", does it come out on F and D?
