Morphology

bust + a + cap

The literal meanings of 'bust' (to break or damage) and 'cap' (a hat or cover) do not predict the violent sense 'to shoot someone'; the slang usage of 'cap' meaning 'shoot' is idiomatic and not compositional. Because this is a slang, idiomatic expression whose overall meaning cannot be derived from the parts and requires prior exposure, it would be opaque to a B1 learner who only knows the constituent words.

Etymology

Bust a cap comes from the image of bust meaning 'break' and cap meaning the small part that makes a gun fire. So, to bust a cap came to mean 'to shoot' someone with a gun.
