Morphology

bustin + ass

The parts 'bust' (to break/force) and 'ass' (butt) combine in a figurative way to mean 'exert oneself', so there is a partial, metaphorical link to working hard rather than a straightforward compositional meaning. Because the sense is idiomatic, informal/vulgar, and requires recognizing a metaphorical extension of 'bust', a B1 learner who only knows the literal words would only partly infer the intended meaning and not reliably predict it.

Etymology

The verb bust ass may come from a strong image: bust meaning 'break' and ass meaning 'butt', so someone works or moves so hard they could hurt their behind. That's why today it means 'work very hard'.
