This is a bold taunt used when a player believes that their opponent’s streak of good fortune has come to an end. In Jamaican dominoes, luck plays a significant role alongside strategy, and sometimes a player may win rounds or make key moves thanks to fortunate tile draws. This taunt is delivered when the speaker feels that the opponent’s lucky streak has been exhausted, and now they will have to rely on skill to continue—something the taunter believes they lack.

By saying "Yuh Luck Run Out Now," the player is essentially warning the opponent that the easy wins are over, and things are about to get more challenging. It’s a way of shifting the mental balance of the game, letting the opponent know that their good fortune is no longer enough to secure victory.

This taunt adds tension and drama to the match, signaling that the real competition is starting and that the speaker is confident in their ability to dominate without relying on luck. It's often used after a turn where the opponent makes a less-than-ideal move, further emphasizing that their advantage has faded.
