The term 'piercing site' refers to the body part that is pierced. The three most common piercing sites are the NAVEL (5 letters), EAR (3 letters), and LOBE (4 letters). Piercing the NAVEL is a popular form of body modification, often done for aesthetic reasons. Piercing the EAR is also a popular form of body modification, and can be done in multiple places on the EAR, such as the LOBE or cartilage. Piercing the LOBE is the most common type of EAR piercing, and is usually done with a stud or hoop.
