Obrbrb (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."
