When an individual eats a plethora of spicy foods, and then the next day takes a huge dump. This resulting burning sensation around the ring of your anus is known as hot ring. Feels similar to a scorching case of herpes.
Last night I ate three atomic peppers from Juan's Taco shack. The next day I had the worst hot ring.
The ring of dirt that accumulates in the back of a fat persons neck. The neck can also appear as though it were a pack of hot dogs leading to the ever unpleasant ring of dirt thus forming the dirt belt.
Check out Riggs, that guy hasn't taken a bath in weeks and has one hell of a dirt belt.
