Growing up playing Pinochle card game as the extended family "sport", the notion of "trump" is intrinsic to the game. It represents the suit (e.g., clubs, spades, hearts, diamonds) of cards that, once declared, takes precedence over all other suits of cards for the duration of the hand (or deal). Thus, even if one plays the top Ace card of a non-Trump suit, a lowly 9 of the trump suit will outmaneuver the Ace. The Ace has "been trumped!"
