†BRAG AND PAIRS, n.phr. “A rustic game at cards” (Gall. 1824 MacTaggart Gallov. Encycl. 88).[Prob. the same as brag, an old English game of cards, possibly the ancestor of poker. When a player held a “pair” or “pair-royal” (three cards of the same rank) in his hand, he threw out a “brag” or challenge to the other players to turn up a “pair” equal in value to his. See brag, s.v. Bragge, n. (1).]
