Sparty No! (alternatively, Sparty, NO!) is a meme based upon the tendency of the Michigan State University Spartans to snatch defeat from the jaws of victory. As a hypothetical example, assume that MSU is undefeated in conference through four games, and heavily favored while hosting a bad University of illinois team. If Sparty were to lose, 10-7, despite dominating the game statistically because they turned the ball over 4 times in the red zone, with the Illini scoring the winning touchdown with about 3 minutes left on an 88 yard fumble return for a touchdown, this would be a classic (albeit extreme) example of Sparty, NO!
