highfalutin

Self-important, pompous; arrogant or egotistical.

It's only a matter of time before some highfalutin developer builds a huge hotel and ruins the scenery.

That one Cajun that moved to Austin is too highfalutin to come back to Livingston Parish. He's over there with that mean bread lady!

Pompous speech or writing.

Don't write so much highfalutin next time.

"We will, we will," shouted the Puddin'-owners; but the Puddin' said sourly: "This is all very well, all this high falutin'."
