This is a direct challenge to another player - normally a Partner - to pass the “poser” or the player responsible for starting the round, often the one holding the double-six in the first round or the previous winner. In Jamaican dominoes, the player who starts the round is called the "poser," and it’s often a point of pride to be the one leading the game in terms of tiles remaining.

The taunt is used when a player feels that the player / partner is struggling or taking too long to figure out their move. By saying, "You Affi Pass the Poser..." they’re reminding the opponent that the game is moving too slowly, and it’s time to make a decisive move to shift the momentum away from the poser.

It adds pressure to the game, implying that the player is being hesitant, lazy or overly cautious. In a fast-paced and competitive environment like Jamaican dominoes, this taunt adds urgency, challenging the opponent to step up their game and take on the poser with confidence.
