A day in which a sporting event takes place and all the senior athletes on that team are starting players. Except for one senior who does nothing wrong and sits all game.
Kid 1 "Do you remember our senior day/night for baseball a few years ago? Kick ass game, so glad we won."
Kid 2 "Oh yeah! I remember that. We all played except for that one kid. Coach must've not gotten the memo about all the seniors playing that day.."
