At the Pig Pen Strib Club in East Los Santos you can easily find a stripper with an extremely skimpy bottom (which is arranged to look like pubic hair). Along with this treat you'll see flames coming out of her nether region = Fire Crotch. "Fire Crotch" is, of course, slang for V.D. of various forms lol.

Another stripper in this same club (a black woman) has a pearl necklace - somewhat less amusing but there nonetheless.
