Ejection means forcing something or someone out suddenly and often with considerable force. When a volcano erupts, it ejects hot lava and ash into the sky. When you press the eject button on a DVD player, a mechanism pushes the disc out so you can remove it.

In sports, ejection means being forced to leave a game as punishment for breaking rules. A basketball player who commits too many fouls or argues too aggressively with referees gets ejected and must leave the court immediately. Baseball managers sometimes get ejected for disputing calls too heatedly. An ejection means you're done for the day, no matter how important the game.

Military pilots have ejection seats that can blast them out of a damaged aircraft in emergencies. When a pilot pulls the ejection handle, explosive charges fire the seat upward with tremendous force, launching the pilot clear of the plane before a parachute opens. This violent ejection can save a pilot's life when their aircraft is about to crash.

The word captures that sense of sudden, forceful removal. Whether it's a player leaving a game, a pilot escaping danger, or a DVD sliding out of its player, ejection means something is being pushed or thrown out quickly and decisively.
