The term 'December Spinner' is a reference to the traditional Jewish game of dreidel, which is played during the month of December. The word dreidel is a seven-letter word that is used in the game. It is a four-sided spinning top with Hebrew letters on each side, and it is used to determine who will win or lose the game. Players take turns spinning the dreidel and then either win or lose pieces of candy or coins depending on the outcome of the spin.
