Inflated, jargon-cluttered prose that fails to communicate clearly.
Coined in 1944 by Maury Maverick, a Texas lawyer, in a memorandum expressing disdain for the "gobbledygook language" of his colleagues. The word was inspired, he said, by the turkey, "always gobbledy gobbling and strutting with ludicrous pomposity."
