Dark Bet

To announce a bet on the next betting round before the card(s) for that round get dealt. The player announcing such a bet "in the dark" must be first to act on the coming round, and the announced bet is binding regardless of the card(s) dealt.

For example, in hold'em a player raises and another calls in position, then before the flop appears the preflop raiser says "I bet $100 in the dark," meaning whatever cards come out, flop action begins with that $100 bet.
