the mid-nifkin ridge, or line of skin that runs from the top of the ass crack, to a man's dick hole. On a woman it runs from her ass crack and up her cunt.
The flavor and musk of the raffi varies. In the southern region it is very dark, stinky, and tastes literally like shit. As you head north, the smell becomes like salt and vinegar chips on a hot sunny day.
