When you get a part of your body pierced in a "circular manner". Meaning you would pierce around your wrist, with "ball end" piercings, creating a bracelet. More commonly seen on the bottom part of one's ear. Where someone "outlines" the bottom part of their ear with piercings.
"Did you see that girl's Run of The Mill Piercing?!"
"Ya! they were like... outlining her bottom ear lobe!"
