hifalutin/highfalutin

THE ADVENTURES OF HUCKLEBERRY FINNの一節です。
Who told you you might meddle with such hifalut'n foolishness, hey? - who told you you could?
この "hifalut'n" は前にもどこかで見たことのある単語ですが、その意味を直ぐには思い出せません。辞書を引きました。"hifalut'n" は普通は "highfalutin" または　"hifalutin/hifalutin'"のスペルが使われるようでその意味は：
・American Heritage Dictionary: Pompous or pretentious: "highfalutin reasons for denying direct federal assistance to the unemployed" affectedly genteel
・Dictionary.com: pompous; bombastic; haughty; pretentious.
語源は多くの単語と同様によく分かっていないようですが、American Heritage Dictionaryに次ぎの記載がありました。
H.L. Mencken, in his famous book The American Language, mentions highfalutin as an example of the many native U.S. words coined during the 19th-century period of vigorous growth. Although highfalutin is characteristic of American folk speech, it is not a true regionalism because it has always occurred in all regions of the country, with its use and popularity spurred by its appearance in print. The origin of highfalutin, like that of many folk expressions, is obscure. It has been suggested that the second element, -falutin, comes from the verb flute--hence high-fluting, a comical indictment of people who think too highly of themselves.
