gobbledygook (n.)

also gobbledegook, "the overinvolved, pompous talk of officialdom" [Klein], 1944, American English, first used by Texas politician Maury Maverick (1895-1954), a grandson of the inspiration for maverick and chairman of U.S. Smaller War Plants Corporation during World War II, in a memo dated March 30, 1944, banning "gobbledygook language" and mock-threateaning, "anyone using the words activation or implementation will be shot." Maverick said he made up the word in imitation of turkey noise. Another word for it, coined about the same time, was bafflegab (1952).
