Games played on the football (or other) field that make sense to band members and no one else, or are used as an irritant for band directors.
After a light rain when the field is slightly damp and other band games are exhausted, some band kids play the Art Band Game: they shuffle their feet around the field to make outlines of vulgar sentences and pictures that the band directors can see when standing at the top of the stands.
Favored types of art are things such as ovaries or penises.
