Morphology
sharp + as + a + bowling + ball
The simile pattern 'as X as Y' is compositional and the meaning follows directly from comparing 'sharp' (clever/acute) with a bowling ball (a blunt, round object), so learners can infer the sarcastic sense of lacking intelligence. This figurative comparison is a transparent, predictable extension of the constituents and is likely accessible to a B1 learner who knows the individual words and the comparative construction.
Etymology
Sharp as a bowling ball plays on a simple image: sharp usually means 'clever', but a smooth round bowling ball has no edges at all. So saying someone is sharp as a bowling ball jokingly means they are 'not smart' or slow to understand.
