Etymology: "Piffle" is probably an imitative word, shaped to sound like the breathy puff a speaker makes when waving off nonsense. The noun means trifling talk, and the verb means to talk in that empty way. "Piffles" is simply its third-person singular form, so "he piffles on about politics" describes someone who keeps producing idle chatter. The verb grew out of the noun, and English often makes verbs this way, as with "fuss." The disdainful, light-hearted tone in your definition fits the word's core sense: trivial talk brushed aside rather than seriously argued with.
