all hell broke loose

Everything went crazy

Chaos erupted suddenly and completely.

The phrase describes a moment when order collapses into pandemonium—a fight, a riot, shouting, things going wrong all at once: The referee made a bad call and all hell broke loose.

The image is of hell's demons escaping their confinement.

Often used for dramatic effect even when describing minor disruptions.
