Off the hook Informal

Freed from an obligation, difficulty, blame, or expected punishment, often unexpectedly or with some relief.

It can describe escaping a literal consequence (like trouble or debt) or simply being let out of a task one didn’t want to do.

The metaphor is drawn directly from fishing: a fish that manages to wriggle free of a hook before being reeled in escapes capture entirely, getting away scot-free after having been, moments earlier, seemingly caught for certain. The figurative extension to any person escaping trouble, blame, or an unwanted commitment follows naturally from this vivid image of a narrow, last-moment escape. Because fishing has been such a widespread, ordinary activity across many cultures for centuries, similar “escaped the hook/trap/net” figures of speech for narrowly avoiding consequences appear in numerous languages, making the general idea difficult to trace to one single origin point, even though English “off the hook” itself is a distinct, identifiable idiom in modern use since at least the 19th century.
