Benchwarmer is a term used in basketball and other team sports. It describes a player who spends most of the game sitting on the bench rather than playing on the court.
The term comes from the idea that the player's body heat warms up the bench they're sitting on.
Benchwarmers are usually Reserve Players who don't get much playing time.
They may be less skilled or experienced than the starting players, or they might be on the team as backups in case of injuries or foul trouble.
