booder (plural booders)
Originally used by young males from what would become the Sugar Hill neighborhood of Hamilton Heights, to the north of Harlem. The vernacular moved with the spread of jazz music through New York City, traveling gradually downtown. Secondhand accounts cite Duke Ellington having used the word to describe the "...booders in those martinis..." and Sidney Bechet saying that his "[expletive] booder is loose," before a concert with Louis Armstrong in 1925.  Usage declined in the mid-50's.
