Nashville Stinkhouse

When one slowly, but surely, crawls inside another's anal cavity until their entire body has been engulfed by the person's rectum. The person inside the rectum then decides to live in said rectum for several years. Once a Nashville Stinkhouse has been initiated it cannot be stopped. It turns out that the human anus is a prime piece of real estate and provides one with a warm home, plenty of space, and enough food and drink to last a lifetime.
