A word invented by a man in Green Bay that means being flat broke, which later became part of a jingle for a fictious store for broke people to shop at. "When you've got nothing in your pocket, Poop Wallet."
I can't afford to go to the movies tonight, I have a poop wallet.
yet another name for someones butt crack.
When that girl in the low rise jeans bent over I could see right down into her poop wallet.
