Why “blatteroon” is a great word
BLATTEROON — [Noun] A senseless babbler or boaster. From the Latin blatero ("babbler, prattler") + the suffix -onis (denoting an agent). Unlike a braggart, which traffics in empty arrogance, or a chatterbox, which merely overflows with talk, the blatteroon is defined by a torrent of foolish, boastful sound that signifies nothing. It is the cacophonous din from a table of drunks each trying to out-shout the other, the ceaseless static of a politician's promise without a plan, or the frantic clatter of a salesman's pitch long after the customer has left—a monument to the human capacity to fill silence with substance-less noise.
noun
