1 definition by Eric Kast

An unintelligable dialect spoken by any person/s attempting to communicate with anyone or anything, real or imagined. Often accompanied by the exaggerated gestures which exasperate the frequently lost meanings behind the initial thought of the individual jibber.
The Lost Book of Jibb contains all the hidden truths of all jibb to be spoken.
