Uncounterfeitable ( poker )

In a high-low game with community cards (as Omaha or hold 'em), describing a nut low hand that still makes a nut low (the lowest possible hand based on the cards showing.) if one (after the turn) or two (on the flop) of the active low cards are duplicated. For example, in Omaha you hold A-2-3-J, and the board is 4-7-8-T. Even if the river is A or 2, you still have the nut low.
