In poker slang, donk can also refer to a weak or unskilled player (a donkey). Outside poker, donk has unrelated meanings in car culture, bodybuilding, and music.

Poker

Donk meaning

Also called

Donk bet, donk betting

Applies to

Poker, especially community-card games and betting-round analysis¹³

Key trait

The bet comes from a player who did not lead the previous round, acting out of position¹

Key points

• A donk bet breaks the expected pattern: the previous round's aggressor is checked to, but a different player leads into them instead of checking.¹
• The term describes the action itself, not the strength of the hand or the size of the wager.¹
• Donk betting is often seen as a sign of inexperience, but can be used deliberately as a strategic move to disrupt an opponent's rhythm.

How a donk bet works

After one player has taken the lead in a prior betting round, another player leads the next round with a bet instead of checking or waiting for the aggressor to act.¹³ This flips the expected order of action: the player who was last to act on the previous street now faces a bet before they can act, forcing them to react from a weaker position.

Slang origin

The term donk is a shortening of donkey, a poker insult for a weak or clueless player.¹² A donk bet was originally seen as the kind of bet a donkey would make — illogical or amateurish. Over time, the term lost some of its insulting edge and is now used descriptively for the betting pattern itself.
