Double-Dealing poker
A cheating move in which a dealer gives more cards (usually
two at a time rather than one) to his confederate or himself
than to the other players. The presumption is the player with
more than the requisite number of cards will form his best five-card
hand, and then get rid of the one or more excess cards (clean
up). The phrase has passed into general usage meaning cheating
someone or the public in general.
