A fancy way of calling a female a whore or ho. And so you don't look like a complete asshole, you dress it in a sophisticated French skirt and custom lucite hooker heels. Unfortunately, a ho is a ho... for sho.
A loose, cheap trollop easily obtained for the price of nothing. I remember when I first read the phrase, "woman of ill fame" and thought, geez that's mean! In today's language that's probably the most endearing insult a ho could ever appreciate.
To get your very own Fun-mouth bucket all you need is to do is, be a married man, scouting for a single Peter puffing hose beast walking the streets! This may cost you several drinks, a possible trip to the free clinic and full tank of gas. Pssshhh, mere coins as long as the wife doesn't find out!
