Morphology

crazy + bone

The meaning 'the area at the elbow that produces a sharp tingling when struck' cannot be derived from 'crazy' (strange) + 'bone' (skeletal tissue); the phrase is an idiosyncratic, informal name for a specific bodily sensation (a variant of 'funny bone'), not a transparent compositional description. Cross-linguistically and semantically there is no obvious link from the constituent meanings to the tactile/nerve sense, so a B1 learner knowing the words would not predict the MWE's meaning.

Etymology

Crazy bone comes from the strange, electric feeling you get when you hit the inside of your elbow. The bone there sits over a nerve, so the hit makes your arm feel crazy, and the phrase now means the spot that gives a sharp 'tingling' or 'shock'.
