breaks loose

Slips the leash

Breaks loose means escapes from confinement or restraint: The dog breaks loose from its leash.

More often, it describes something sudden and chaotic beginning: All hell breaks loose, A storm breaks loose.

The image is of something previously contained—whether physical, emotional, or situational—suddenly becoming uncontrolled.
