pierceaholic 

Somebody with WAY too many facial piercings. If you have both eyebrows, your tongue, AND more than one piercing in your lip, you are a pierceaholic and you look like an idiot.
Pierceaholics are usually, but not always, employed at your local tattoo and piercing parlor.Sometimes they are just gothic.
