Morphology

bob + under

The meaning 'to disappear suddenly and briefly beneath the surface' is directly and predictably composed from 'bob' (quick up-and-down movement) plus 'under' (beneath), so the sense follows straightforward spatial-motion semantics. This verb + preposition pattern is common and cross-linguistically transparent, so a B1 learner who knows the constituents can infer the MWE's meaning.

Etymology

Bob under comes from the simple picture of a cork, fish, or duck that bobs on the water and then goes under for a short time. So, it now means 'to disappear suddenly and briefly beneath the surface'.
