This is a common expression that results from an exciting ultimate frisbee play. For example, when one teammate throws a long pass that is secured in the end zone by an amazing display of athleticism, one would exlaim, "POOP DOLLA!"
Danny throws a long pass to Phil and Aly exclaims "POOP DOLLA!"
When you take a five doller bill and wipe your ass with it and throw it on the ground. A stranger comes by and picks it up with said shit on the bill and you yell Poop Doller.
(Great for Balcony fun!!!)
Jim was so desperate for crack he didn't care about the assholes yelling poop doller when he found five dollars.
Taking a 1 dollar bill and using human poo if possible, or dog poo, smearing it on the dollar and placing it on the ground in a public place preferably with drunk people(concerts, sporting events, college campus) and wait for someone to pick it up
We placed the poodollar down in the parking lot of the concert and a drunkkid came by and put it in his pocket
