piercing poker

A person who unconsciously reaches out to touch other people's new piercngs, often without permission. They aren't doing it to be a douche, they just kind of don't realize they're doing it.
Similar to a personal space invader, but only momentarily.

Me: Man, Sherry was molesting my industrial today. It kind of hurt, actually.
Bud: Yeah, she's a piercing poker.
