Where did the popular urban idea of "throwing the deuces" come from?

deuce

c.1475, "a roll of 2 in dice," from M.Fr. deus, from L. duos (nom. duo) "two." Became a mild oath by 1710, about 50 years after it was first attested in the sense of "bad luck, the devil, etc.," perhaps because two was the lowest score, and probably by similarity to L. deus and related words meaning "god." Low Ger. had der daus! in same sense 16c., which probably influenced the Eng. form.
