Bush league
From Wikipedia, the free encyclopedia
Bush league is a general term used to describe an action or thing as being amateur, inferior or crude. In a literal sense, it refers to a low quality minor league in baseball not associated with any of the major league teams. The term originated from the state of minor-league fields that often were ringed with shrubs and bushes.
The phrase sounds similar to the NASCAR Busch Series, sometimes known as the "Busch League," with the same reference to being minor league or inferior. However, popular usage far predates the creation of this organization.
