Morphology

laugh + one's + head + off

The meaning 'to laugh very loudly' is a conventionalized hyperbolic idiom and cannot be derived compositionally from 'laugh' + 'one's head' + 'off' — the literal idea of removing a head does not map to intense laughter. Because the relation is metaphorical and unpredictable from the parts, a B1 learner who only knows the constituent words would not reliably infer the idiomatic meaning.

Etymology

Laugh one's head off comes from a wild image: imagine laughing so hard your head might come off. One popular story says people used that picture to show very strong laughter, so the phrase now means 'to laugh very loudly'.
