look up any word, like rimming:
A piercing located on the top lip, in the middle, just below your septum.

Generally worn with a labret post, Medusa piercings are incredibly painful.

Greek legend has it that she was once a gorgeously hot woman with beautiful hair. She had an affair with the Greek god Zeus, but Athena, who was Zeus's wife at that time, found out and cursed Medusa by turning her hair into serpents and giving her the gift of petrifyng anyone who stares into her eyes.
But other than that, sex with Medusa is fantastic. Just make sure she has her sunglasses on.

Medusas, are in fact, very painful. They are not very common, but can still be found adorned on the bodies of body modification culture.
She pierced her Medusa while at the Body Art Expo.
