What is Gay Berets?
1.
nickname of the sousaphone section of a high school or middle school marching band due to three standard and mandatorily successive characteristics:
1) they're all gay by definition.
2) they wear berets while they march because standard aussie hats or shakos don't fit under their sousaphones.
3) there is assonance that makes the term catchy.
