A term in poker, usually of the online variety. A D-Raise is when a player is the last player to act around the table after all other players have bet or called the existing bet, and instead of just calling or checking like everyone else and getting to the next card, the D-Raiser bets the minimum amount, causing the entire cycle of betting to have to repeat itself. It can be especially frustrating in games with a large number of players at a table.
