A tennis hopper is called a "hopper" because it resembles a container that "hops" or holds tennis balls. The design typically features a spring-loaded mechanism that allows players to easily dispense balls by pushing down on the handle, making it convenient for practice and feeding balls during drills. The term reflects both its functionality and the way it can facilitate quick access to tennis balls.
