Usually a woman who will poop her pantie for a man when paid an agreed upon amount of money. This gives some men a sexual arousal. Being a poo 'ho or poo fetish 'ho can be financially lucrative for the woman, primarily because it is a rather specialized form of prostitution.
I had Heather over last night. She's that poo 'ho a guy at work told me about. She looked fine! Short black skirt, white panty hose and black high heels. She lifted her dress, and did a huge load into her panty hose. I got so hot I came all over myself. Before she left she gave me a blow!
