The term 'BASKETBALL HOOP ATTACHMENT' refers to a NET, which is a three-letter word. A basketball hoop attachment is a NET that is attached to the rim of a basketball hoop. It is designed to catch the ball when it is shot and prevent it from bouncing off the rim. The NET also serves to slow down the ball's momentum as it passes through the hoop. The NET is usually made of nylon or polyester and is typically white in color.
