A ring a pimp wears. Usually gaudy. Often used to make a pimp-slap hurt more and maybe cut. A special kind involves 5 rings - 1 per finger and spells out "bitch" backwards - that way if the hoe don't have his money, and he slaps her "bitch" is imprinted on her cheek or forehead.
"check out my new pimp ring. It cost $1000. A whole days earnings from one of my hoes."
A form of error message on the Xbox 360. The Red Ring of Death replaces the Ring of Light, the green circle surrounded the power button. The red lights indicate a sort of error message and the number of lights and placement of them mean different things. The worst would be three lights flashing, with the top-right not illuminated. In this situation, it means the 360 is suffering hardware failure.
