There are several conflicting theories where the name Craps originates from. One is: The roll of two ones (1-1) was called "Snake Eyes" or "Crabs" in a regional lingo of the dice game Hazard which later evolved into craps. Another theory is that the name stems from the french word "crapaud" (meaning toad) referring to the way the game way played in the streets in the 18th century - people crouched over the floor on the sidewalk.
