The act of forcing a player to play the entire game (without resting on the bench) against their will as a form of punishment.
Derived from the adult recreational sporting world (or beer league), used in high intensity sports (such as hockey or basketball) played recreationally when out of shape older players would prefer to rest (or be benched).
At our late night beer league hockey game, Joe got reverse benched because he forgot to bring beer to the game. Half way through the game, he was so gassed he was puking in the garbage can because he wasn't allowed to rest.
