Hot Ring 

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.

Blood Ring of Death 

Noun. When a man has sexual intercourse with a female during the peak of menstration, he then pulls out his drenched penis and inserts it into the females mouth leaving a red ring of blood around her lips.

Either Jenna got some new lipstick or she is on her period, cause it looks like she got the blood ring of death.
