Conbledegook

From Conbledegook

Conbledegook is a term Alex Holden invented when he was writing this glossary to describe the obscure and confusing (to mundanes and neofans) vocabulary used by fans who attend cons, and in particular Eastercon. Not just international fanspeak, but also Eastercon-specific terms like Dave Lally programme and Beyond Cyberdrome. It's a portmanteau word formed by combining "convention" and "gobbledegook".
