Poker Party Terminology - D Dead
A dead card is a card that is no longer available to help you. In seven card stud, for example, a pair of kings in the hole is less strong if the two remaining kings are two other players' door cards, and therefore dead.
Deal
To deal is to give out the cards during a hand. The person who does this is called the dealer. At most public cardrooms, a dealer is hired for this purpose (and for generally running the game). At most private games, players take turns dealing.
To be dealt in is to be given cards during a hand. To be dealt out or dealt around is not to be given cards.
Dealer's Choice
A format in which the dealer is allowed to select the particular poker game that will be dealt. Sometimes this means before each hand, although a more sensible system (since in many games the dealer has a positional advantage) is one in which players take turns choosing the game for an entire round.
Declare
Declare games are games in which you must declare the value of your hand in order to claim the pot. A typical example is a high-low split game in which you must declare before showdown whether you are claiming the high, low, or both pots (typically if you declare both you must win both in order to claim either). Declare games are played almost exclusively in home games. In most if not all cardrooms, cards speak.
Deuce
Twos are sometimes called deuces. So 22277 can be called deuces full of sevens.
Deuce to Seven
In a game played for low, deuce to seven usually means that the best low hand is simply the worst poker hand. If you haven't figured it out already, that hand is 75432, with no flush. Deuce to seven lowball is also called Kansas City, or Kansas City lowball. See also ace to five.
Dominate
A starting hand that will almost always beat another starting hand is said to dominate that hand. For example, in hold'em, AK dominates K2. Most of the time K2 makes a playable hand, AK will make a better hand. However, a 2 might still spoil the party.
Door Card
The first card dealt face up to each player in seven card stud is the door card.
Double Belly Buster
A double belly buster is a hand with two inside straight draws. For example, 79TJK can become a straight with an 8 or a Q. It's roughly equivalent to an open-ended straight draw, except that the double belly-buster is more deceptive, and people often fail to notice that they have one (especially in cases such as when the 7 in the above example shows up on a later street, and the player is focused on the gutshot they already had).
Draw
The word draw has slightly different meanings in different contexts, although generally it has something to do with receiving more cards, with the hope of improving your hand.
Draw games are games where at some point during the hand you are allowed to discard some or all of your cards, to be replaced from the deck. Drawing two is thus exchanging two of your cards. "The draw" is the point during the game at which players may do this. By default, when someone asks you if you want to play some draw, they usually mean five card draw.
In other poker games, drawing simply means staying in the game with the hope of improving your hand when more cards come (as opposed to with the intention of seeing if your hand is best). A draw means a way to improve. For example, if you have four suited cards, you have a flush draw. When you stay in a hand with the hope of improving, you are said to be "on a draw." You are also said to be "drawing to" the hand you hope to make. For example, in lowball, if you hold K7642 and draw one, you are drawing to a (ragged) 7 (i.e., a 7 low).
Draw Dead
To draw when it turns out you would lose even if you hit your draw. Most trivially on the turn in hold'em, if you have a fourflush with KQs but someone else holds A5s and has already made a pair of aces, you're drawing dead. Whenever you make your flush, they make a better flush.
Draw Out (on)
To draw out on someone is to outdraw them.
Drawing Hand
A hand with which you expect to be on a draw is a drawing hand. Suited connectors in hold'em (e.g., QhJh) are drawing hands, since while they make strong hands (straights and flushes) relatively often, they will rarely make them on the flop.
Drop
To fold is to drop. To drop is to fold.
