From Menken:
Of adjectives the list is scarcely less long. Among the coinages of the first half of the century that are in good use today are non-committal, highfalutin, well-posted, down-town, two-fer, played-out, flat-footed, whole-souled and true-blue. The first appears in a Senate debate of 1841; highfalutin in a political speech of the same decade.
