President to President: H.W. Bush Calls Trump a 'Blowhard'

Blowhard swaggered to the top of our lookups on November 4th, 2017, following reports that a forthcoming book quotes George Bush, 41st President of the United States, as describing Donald Trump thusly.

Former President George H.W. Bush has a blunt assessment of Donald Trump: "He's a blowhard." And his son, former President George W. Bush, has harsh words for his Republican successor as well: "This guy doesn't know what it means to be president."

We provide two definitions for blowhard, neither of which is complimentary. Both senses appear to have originated in the middle of the 19th century; one is braggart and the other is windbag.

Professional "Blow-hards."
Among the various and multiplied phases of human character, there is one class which is common to an almost unprecedented extent in California. Upon every street corner—in every public place—in the avenues of business, and especially in the arena of politics, gentlemen of the class referred to are to be found, conspicuous among the crowd. Their chief trade is to manufacture opinion—deceive the unwary—magnify their own importance, and impose upon the community a bogus sentiment for the genuine article. Those who compose the class we refer to, in Bowery parlance, are known by the not very euphonious, yet expressive soubriquet of "Blow-hards."
