as opposed to the toe ring, the earring, the finger ring, and the ultimate dicky do ring
The initial purpose of the nose ring was to add a place to attach a log chain to a misbehaving Bull. When the bull acted up or threatened to "charge", all you had to do was step on the chain. The bull's behavior would immediately improve--because it really hurt. The introduction of the nose ring in humans, was like most fads, just bizarre acting out to shock the older generation (parents?)
I dunno for looks.
I have no idea the purpose of that
to show off a persons nosiness ive got one:)
