So I keep looking at pictures of Tauren and thinking “why do they have a nose ring” so I go to wikipedia and:

The nose ring assists the handler to control a dangerous animal with minimal risk of injury or disruption by exerting stress on one of the most sensitive parts of the animal, the nose. Bulls, especially, are powerful and sometimes unpredictable animals which, if uncontrolled, can kill or severely injure a human handler.

Kinky.
