Morphology

flash + mob

The idea of a sudden or brief gathering is directly suggested by 'flash' (a very short time) combined with 'mob' (a crowd), so a B1 learner could plausibly infer a quick assembly. However, the specific conventionalized sense — a coordinated, often performative meeting that disperses quickly (and its association with organizing via social media) — is not fully predictable from the parts, so full understanding usually requires prior exposure.

Etymology

The noun flash mob comes from the words flash meaning a very quick event and mob meaning a crowd. People used phones and online messages to meet suddenly, do a short surprising performance, and then leave, so the name fits a crowd that appears and disappears quickly.
