One of the massively many attendants to the first 10 or so editions of the Benicàssim International Festival for independent -indie- music (FIB: Festival Internacional de Benicàssim) at the esat coast of Spain by the Mediterranean sea. It does not imply being a lier or a bastard, as some other definitios of this word suggest, but it conveys a sense of melomany and rave to a certain extent.

Many fibbers later became specimens of other urban tribes, such as grunges, clubbers, moderns or hipsters. The FIB has now evolved, changing location, camping facilities and artist selection policies, but it is still massive.
