The area between the ass and the scrotum. It is called "Taint" because it Taint your ass and it Taint your nuts!

ety. (v) Taint is a whimsical distortion of "it isn't" > it ain't > taint.

(n) 1. The taint is the stretch of skin at the inferior surface of the perineum (bottom of the crotch). 2. In males the taint is the region between the anus and the scrotum; in females it is the region between the anus and the vagina.
It taint part of the pussy and it taint part of the ass; it's right between them.

A taint is the stretch of skin found only on women between the pussy and the asshole. The term originated from the phrase "taint an asshole and taint a pussy." In contrast the skin between the scrotum and asshole on a man is referred to as the "gooch" and first known usage is a reference to Bob "the gooch" Guccione the owner/publisher of Penthouse. His employees and acquaintances couldn't quite decide if he was more of an asshole or a dick, a general consensus eventually formed that he was both and "everything in between," hence the gooch.
Q: Hey lady, do you know why the piece of skin between your vagina and anus is called a taint?

A: Because it taint a pussy, and it taint an asshole.
The area between the nutsack and asshole that prevent a man from shitting on his nuts. See durf.
If it wasn't for the taint, my nuts would reek of poo!

the small patch of land between the punani and the asshole. Derived from "it aint", as in "t'aint one, t'aint the other"
With thumb and forefinger buried to the hilt, I could do little more than rub her taint...
