bafflegab
noun verbose language that is difficult to penetrate and impossible to understand. The term, by all accounts, was coined by Milton A. Smith of the United States Chamber of Commerce. Smith defined the term as 'Multiloquence characterized by consummate interfusion of circumlocution or periphrasis, inscrutability, incognizability, and other familiar manifestations of abstruse expatiation commonly utilized for promulgations implementing procrustean determinations by governmental bodies'
