Piercing
Using a sharp instrument, usually a needle, to make a temporary or permanent hole through an earlobe or other body part.
Humans have practiced piercing for body decoration since prehistoric times.
Unless it is performed using a sterile needle (preferably disposable), piercing can carry a risk of infection.
A piercing should be kept clean; antibiotic cream may be applied if the area becomes inflamed.
