Dear Mark:
The question about "Back Door Little Joe" is referring to the song "It Was A Good Day" by Ice Cube. The lyrics in question are:

…With the seven, seven-eleven, seven-eleven, seven
Even back do'm little Joe. I picked up the cash flow.

An educated guess as to the reference would be that since they are likely not playing craps on a craps table, but rather on the ground and shooting against a wall or door, Cube is likely referring to the fact that he was able to roll "little Joe" off the "back do.” Gavin O.
