What is the origin of ‘winner winner, chicken dinner!’?
The phrase “winner winner, chicken dinner” is derived from the American traditions of gambling. In general it means to have won something. Specifically it is a phrase often used by poker players who have that last card needed for their hand to make them a winner and get their greedy little hands on all the loot in the pot – winnings based on number of people playing, but generally this term just means they’ve won and are ready for everyone else to pay up.
The meme’s originator may never be known with complete certainty, but some sources suggest that it was very well accepted among army personnel by WWII because gambling wasn’t prohibited for servicemen at the time as long as each game involved no more than five dollars minted coins
