A (usually) enslaved woman who is paid for the public (meaning men) use of her vagina. Contrary to a large chunk of public opinion, most of these poor women are NOT doing this of their own volition. They are usually exported from 3rd world countries by amoral people who are interested in furthering their own interests at their expense.

"heheh, right on old fellow, right on."
