A stupid name trendies call a tounge piercing. The jewelery used in a tounge piercing isn't a "ring" or a "stud" at all, it is called a barbell. So whenever you hear someone use this phrase, kindly punch them in the face, because anybody seriously involved in piercing is sick and tired of hearing this. See also belly ring.
"Lyke, I totally got a tounge ring on saturday! I'm soooo kewlll :P"
