look up any word, like fellated:
 
1.
Circular Piercings inserted into piercings/pierced areas. Commonly used in ears, bottom lips, eyebrows, noses, nipples and occasionally the belly button, penis and vagina.

Usually they are a circular piece of metal, with a ball holding the two pieces closed so the piercing won't slip or fall out.

Rarely are they silver, gold or glass.
A : "Do you have anything better to put in my ears? All i have are these boring studs.."
B : "Well I just bought some neon captive hoops the other day"
