Dirty Inch 

The truly un-named distance between the asshole & corresponding genitalia, for men the nuts & women the pussy. Always the victim of shrapnel from sex, exercise & any other body fluid exuding activity, hence the name.

After going at it for a while her dirty inch was gettin' a little gummy.

dirty inch 

The anus and surrounding flesh, as it is about 1" diameter. Not necessarily clean nor dirty, it is called the 'dirty inch' because it is the excretory region on the human body.

I was doing her from behind and without warning I slipped it into her dirty inch.
