Morphology

flap + one's + gum

The phrase evokes a literal image — 'flap' (move quickly) + 'gums' (part of the mouth) — so there is a visible link to mouth movement and thus speaking. However, the meaning 'talk a lot / gossip' is a colloquial, metaphorical extension (moving gums → excessive chatter) that is not fully predictable without prior exposure, so a B1 learner would likely find it only partially transparent.

Etymology

The idiom flap one's gums may come from the image of a mouth moving like a bird's wings: flap means to move up and down and gums are part of the mouth, so it looks like someone is making noisy mouth motion without saying anything important. That's why it means 'to talk a lot', often about unimportant things.
