Morphology

flump + down

The meaning 'to sit or fall heavily and suddenly' follows directly from combining 'flump' (to drop or set down heavily) with 'down' (to a lower position/direction). This verb + particle composition is a standard, compositional English pattern, so a B1 learner who knows both constituents should be able to infer the MWE's meaning.

Etymology

Flump down likely comes from the soft, heavy sound flump makes when something drops into cushions and the word down meaning 'to a lower place'. Imagine collapsing into a chair with a quiet, heavy plop; that's why flump down means 'to sit or fall heavily and suddenly', often because you are tired.
