ITâS been quite a while, but GUBU is making a comeback. An acronym for grotesque, unbelievable, bizarre and unprecedented, the phrase was paraphrased from a comment by then Taoiseach Charles Haughey while describing a strange series of incidents in 1982 that led to a double murderer being apprehended in the house of the attorney general. It was a bizarre happening, an unprecedented situation, a grotesque situation, an almost unbelievable mischance.
