He could clearly remember the observations of one Viennese criticaster, as he put it, which were published in the Presse, to the effect that the actors at the Burgtheater could neither walk nor speak, or at least that they could not do both at once.
-- Thomas Bernhard, Woodcutters, translated by Suhrkamp Verlag, 1987
Origin
Criticaster entered English in the late 1600s from critic and the diminutive suffix -aster which means something that imperfectly resembles or mimics the true thing.
