Slip ( poker )

1) Pass, with the implication of sandbagging (Playing a strong hand as if it were only a fair one.); often followed by it. If a player says, "I'll slip it," he's trying to give the impression that he passed a good hand, probably because in reality he passed a medium hand with which he doesn't want to have to call a bet. 2) Palm a card, for later introduction into the game.
