Ampallang piercing
Ampalling is a form of male body piercing that occurs on the penis. It usually runs perpendicularly through the glans from the right centre - to the left centre. It can either go through the urethra or above it.A modified form is shaft ampalling, the difference being, it occurs in the shaft, as opposed to the glans. Thus, a potential for the ampalling ladder is created. Another form is the apadravya piercing, or even the Magic Cross piercing.
The piercings origin may be found in Polynesian culture, specifically the Dayak people.
