This is a sarcastic taunt often used when someone makes a misplay by starting the game with the wrong tile. In Jamaican dominoes, the player with the Double-Six is supposed to "pose" (or start) the game in the first round, and if a player isn't paying attention and places a different tile, this taunt is thrown their way to highlight their mistake.

It’s a playful but direct way of calling out the opponent’s lack of focus or game awareness, essentially saying, "You’re not paying attention!" The taunt refers to the rules of dominoes, where starting the first round with the Double-Six is a must, and any other tile being played first disrupts the proper flow of the game. The exclamation adds to the dramatic irony, as the player mocks the blunder in a lighthearted but teasing manner
