AKA Flibber me Gibbet, Flibbertigibbet, and Flibber the Gibbet.
Flibber-de-gibbet is from Middle English flipergebet, apparently a nonsensical word meant to represent meaningless chatter, from 1549, where it describes a "chattering gossip, flighty woman."
There is some suggestion that the term may also relate to a flibbering jib, where flibber means to flap randomly in the wind, and the jib (originally "gibb," dating back to the 13th century)is the foremost sail of a ship. The loose, flapping jib would then make the flapping sound much like meaningless chatter as defined in the 1549 definition.
