CORONCON

from Fancyclopedia 2

(Bulmer) The London con of 1953, named after some mundane event or other that took place that year; christened thus ten seconds after the proposal for a con in 1953 had been mooted (at the '52 con, also in London). It was held at the Bonnington Hotel during the same weekend the Queen's Army Schoolmistresses Reunion [!!!] took place there. Site of the Roofcon, and notorious for the quelling by unplayful porters of night party sessions.
