One of the most widely accepted theories about the origin of the name “craps” is that it is derived from the French word “crapaud,” which means “toad.” This connection is thought to refer to the way players crouch or squat around the table while playing the game. Another theory suggests that the name is a play on the English word “crabs,” which was a term used to describe certain losing rolls in the game of hazard, the precursor to craps.
