A bet made by the first player to act postflop which is typically very small in relation to the pot size and often the minimum bet. This bet is made by the player who is not the initial aggressor in the hand. Example: Blinds are 1,000/2,000 with a 2,000 chip big blind ante. The Button raises to 4,000 and and the Big Blind calls, making the pot 13,000. On the flop the Big Blind Donk Bets for the minimum bet of 2,000.
