In which game might you have a "double belly buster"?

A double belly buster is a hand in which you have 2 inside straight draws. Similar to an open ended straight draw (OESD), there are 8 outs to complete your straight draw. An example is being dealt the hole cards Jack and Ten when the flop is Ace-Queen-Eight. Although not open-ended, any King or Nine will complete the nut straight.

Texas hold 'em (also known as Texas holdem, hold 'em, and holdem) is one of the most popular variants of the card game of poker. Two cards, known as hole cards, are dealt face down to each player, and then five community cards are dealt face up in three stages. The stages consist of a series of three cards ("the flop"), later an additional single card ("the turn" or "fourth street"), and a final card ("the river" or "fifth street"). Each player seeks the best five card poker hand from any combination of the seven cards of the five community cards and their two hole cards.

Players have betting options to check, call, raise, or fold. Rounds of betting take place before the flop is dealt and after each subsequent deal. The player who has the best hand and has not folded by the end of all betting rounds wins all of the money bet for the hand, known as the pot.
