ribroaster

from The Devil's Dictionary (1881-1906)
RIBROASTER, n.  Censorious language by oneself concerning another. 
The word is of classical refinement, and is even said to have been
used in a fable by Georgius Coadjutor, one of the most fastidious
writers of the fifteenth century -- commonly, indeed, regarded as the
founder of the Fastidiotic School.
