How it's used
Implies that someone's sudden erratic or irrational behavior is so extreme that it seems chemically induced. It is a sharp, often confrontational way to question someone's sanity or judgment during a heated moment. While it carries a strong tone, it is frequently used among close friends or family to tease someone who is acting uncharacteristically bizarre.
Examples
Are you crazy? Why are you saying things like that?
He seems to have gone crazy today, laughing non-stop.
