Definition: In everyday usage, "cup" is simply another name for the hole on the putting green - the place where every golfer is trying to get his or her golf ball.
In more specific usage, "cup" is the liner-slash-receptacle that is sunk down into the hole on the putting green, usually made of a white plastic. The cup cradles your ball after it finds the hole, and is fitted to keep the flagstick upright.
