1540s, "chattering gossip, flighty woman," probably a nonsense word meant to sound like fast talking; as the name of a devil or fiend it dates from c. 1600 (together with Frateretto, Hoberdidance, Tocobatto). OED lists 15 spellings and thinks flibbergib is the original.[flibbertigibbet etymology, flibbertigibbet origin, 英语词源]
