Blank

Often used to refer to a community card in hold’em or Omaha that does not appear to affect the relative strength of players’ hands. For example, if the flop comes A♠K♦8♦ and the turn the 9♠, the 2♥ on the river will be described as a “blank” as it completes no draws and players remaining in the hand aren’t likely to be helped by the deuce.
