Morphology

become + prickly

The verb 'become' simply signals a change into the state described by the adjective 'prickly', and 'prickly' already means touchy or easily offended. This compositional pattern (change into + adjective meaning 'irritable') is direct and predictable, so a B1 learner who knows both words will readily infer the idiomatic meaning.

Etymology

The phrase become prickly comes from the picture of a person behaving like a hedgehog or a cactus, showing sharp points when they feel threatened. So when someone becomes prickly they react in an annoyed, defensive way.
