Septum piercing
A piercing through the soft tissue between the nostrils.
Also: bullak
A septum piercing passes through the thin strip of soft tissue at the front of the nasal septum, not the cartilage. Rings or bars hang below the nose. It has a long history in many places: among Indigenous peoples of Australia, Papua New Guinea and the Americas, and in Nepal and among some Indian communities, where a hanging septum ornament is called a bulaq or bullak. It became a Western fashion in the 2010s.
