"Game over" is a message in video games which signals to the player that the game and an attempt of playing the level has ended. It is usually received negatively in a situation where continued play is disallowed, such as losing all of one's lives or failing a critical objective. However, it sometimes also appears after the successful completion of a game, usually ones designed for arcades. The phrase has since been turned into quasi-slang, usually describing an event that will cause significant harm, injury, bad luck, or even death to a person.
