How it's used
Used to describe someone acting in an irrational, erratic, or highly unpredictable manner. It is often used as a rhetorical question to express frustration or disbelief at someone's bizarre behavior. While it literally references nerves, it is strictly used as a colloquial insult or observation of behavior rather than a clinical term.
