"King Me!" is a move that does not appear in chess, but rather Checkers, the natural rival to chess. In checkers, after a series of moves, one player can demand of the other that they "King" them. To do so, after the aforementioned series of events which may take place in the game of checkers, the "King-er" must admit that the "King-ee"'s checkers abilities are divinely ordained by Our Heavenly Father.
It is reported that Charlemagne once yelled this phrase at Pope Leo III, thus leading to his being crowned Emperor.
