bloviator

1. A public figure, such as a politician or an actor, who makes outlandish, strident statements on issues, thinking that the average man will care about their opinions.

2. Someone who pontificates about issues of which they are uninformed, yet pretend to be expert.

3. Pompous blowhard, using their celebrity to speak about topics on which they are totally unqualified.

Bloviate is closely associated with U.S. President Warren G. Harding, who used it frequently and who was known for long, windy speeches. H.L. Mencken said of him, "He writes the worst English that I have ever encountered. It reminds me of a string of wet sponges; it reminds me of tattered washing on the line; it reminds me of stale bean soup, of college yells, of dogs barking idiotically through endless nights. It is so bad that a sort of grandeur creeps into it. It drags itself out of the dark abysm of pish, and crawls insanely up the topmost pinnacle of posh. It is rumble and bumble. It is flap and doodle. It is balder and dash."

To discourse at length in a pompous or boastful manner.

A key attribute to those that sell. To pretend to understand technical subject matter and sell it to others even dumber then oneself.

The word that Ludwig learned from Schlatt to justify his 80k English Degree.
