Body piercings, especially facial piercing, that mark the wearer as someone's "bitch". Often used in prison, gangs, or by pimps of homosexual male prostitutes to show ownership. The "owner" or pimp makes the ring highly visible to show ownership, and also easy to grab onto to inflict pain on the "bitch".

A group of girls that revel in their shared bitchiness. Most common in Asian girls.
Look at that bitch ring of Asian girls all walking together. It makes me want to backhand them.
