Nussy

Vertical rolls of fat on the neck of a dog, most often found on a hound dog. These vertical fat rolls are always covered with hair and resemble vagina lips. Their placement on the neck combined with the anatomy they represent gives us the word....Neck Pussy or "NUSSY"

No, you can't fuck the nussy but I'm sure some have tried. Sick bastards!

Check out the nussy on that bitch.
