A toungue stud! It was when i went on holida with my friends a while back (ears and years) and it was the kind that would glow up under ultra violet lights!! Thing is i had already wore it the nights before and someone took it used! I know it was taken coz the place it was kept was the appartment safe and 4 of us had a key and 3 out of the 4 of us have out tongues pierced. :lol: Gross if someone wants to wear t after me :lol:
