How it's used
Describes a sudden, irrational, or uncharacteristic outburst of behavior rather than a clinical diagnosis of mental illness. It often implies that the person is acting out of character or has temporarily lost their sense of judgment due to extreme anger, excitement, or panic. The term carries a slightly dramatic tone, making it common in arguments or when describing someone acting erratically.
Examples
Have you lost your mind? Why are you throwing everything away?
He ran out into the road like a madman, it was really dangerous.
