Which procedure does NOT fall under body piercing as defined in common terms?

The procedure that does not fall under body piercing, as commonly understood, is ear piercing. In many contexts, ear piercing is often viewed as a distinction outside of the broader category of body piercing, primarily because it has become a conventional practice that is widely accepted and performed from an early age. Ear piercings are typically done for decorative purposes and regarded as a rite of passage, especially for children, and are often performed with the use of piercing guns in retail environments.

In contrast, other types of piercings, such as nostril, cartilage, and navel piercings, are generally considered more specialized forms of body modification and are associated with specific subcultures or aesthetic choices. These procedures may be performed for various reasons, including personal expression and adornment, and typically require a higher degree of skill and care in aftercare than traditional ear piercings. Understanding this distinction is important in the context of regulations and classifications surrounding body art practices.
