Open Blind, Raise Blind, Reraise Blind ( poker )

1) The term usually applies to a draw game, generally lowball, and is often shortened to OBRBRB. A game in which the first player to the dealer's left blinds the pot, the next player raises blind before getting his cards, and the next player raises before getting his cards. Since this puts six bets into the pot before the cards are dealt, the effect is to increase the action of the game. Often shortened to re-raise, and sometimes called raise blind.
2) This is usually part of a proposition. A player who asks another, "open blind, raise blind, re-raise blind?" is saying, "I will open the pot blind and re-raise you back blind if you promise to raise blind."
