crap-haggler

Any person, not necessarily homeless, that will haggle bargain with you for your feces (chocolate gumdrops).
Someone that will approach you seemingly out of nowhere, after having shadowed you, analyzing in secret the remnants of your stanking poo, perhaps left behind in public restrooms.
They will attempt to get you to lower your standard fee - don't! Rob them blind with your penchant for poo pricing!
