Well I didn't know that!

Just as an aside, the terms 'fancy man' and 'fancy woman' I used to hear when I was a child but not so much now, in those days it meant a girlfriend/boyfriend or lover or someone you were seen with. But from what it seems from the site describing Victorian occupations, 'fancy man' originally meant a pimp and 'fancy woman' meant a prostitute. Now either those terms  meant something else and were used as slang or they were created to describe both those occupations but gradually changed with usage.
