Craps name origin.

My friends and I were discussing the different names for prop bets or any other slang terms for any numbers on the craps game and one stuck out. Skinny Dugan. We just want to know the origin of the term. I've asked the BoneMan over at nextshooter.com but he doesn't know it neither.

Other interesting slang names are that I want to know the origin of:

Nina Ross or Nina from Pasadena (9)
Little Joe from Kokomo (4)
Phoebe (3)

Anyone with other interesting origins please feel free to share.
