A lowly rodent who, out of desperation, has learned to live alongside man by occupying one of our less-than-ideal structures, the outhouse.

Eternally mocked by the rest of the animal kingdom for it's choice of habitat, it passes through life barely noticed by man except in this phrase: "Poorer than a shithouse mouse"

Clearly indicating that the individual described does not even possess the meager funds required to reside in an outhouse.
After being denied $20 from the ATM machine for lack of funds: "Damnit, I'm poorer than a shithouse mouse"
