No, no, no.  Gee, you're such a bunch of clueless newbies.  It's just a code like "roses", "kisses", "BBBJ" and "CFS".  
"Gentlemen" refers to pictures of dead presidents*.
"Distinguished" means U.S. Grant.
 
"Upscale" means Ben Franklin.
 
Now you know when a lady says she only caters to "Distinguished and Upscale gentlemen,"  She means "I'll suck your dick and fuck you for $150."
*Yes, I know Franklin was never president.  The lady with the "distinguished and upscale" ad doesn't.  
"Benjamin Franklin - the only president of the United States who was never president of the United States."
