A piercing is a body modification practice that involves creating a small hole or perforation in the skin or a body part, typically using a needle or other specialized equipment. This hole is then usually adorned with jewelry, such as rings, studs, or barbells, that is inserted through the piercing to enhance or decorate the area.

Piercings can be performed on various parts of the body, including but not limited to the ears, nose, lips, eyebrows, tongue, navel, and various locations on the body's surface. Piercings can serve aesthetic, cultural, or personal purposes, allowing individuals to express their individuality and style.

The process of getting a piercing should be performed by a professional piercer using sterilized equipment to minimize the risk of infection or complications. Proper aftercare is essential to ensure the piercing heals correctly and without issues. Piercings have been practiced for centuries and have cultural, spiritual, and aesthetic significance in different societies and time periods.
