Exaggeration, then, is one easy artifice of effect. Another is the constant repetition of certain words and phrases which have lost their meaning by detrition and are known to all. Not to be disappointed is sometimes as pleasant as to be surprised. A catchword passed from one to another is often a signal of sympathy, and many a man has been taken for a wit merely because his tinkling brain has given back the echo which was expected. In stereotyped phrases, in ready-made sentences, in the small change of meaningless words, the American language is peculiarly rich. "To cut ice," "to get next to," "straight goods," {*}--these and similar expressions, of no obvious merit in themselves, long ago lost their freshness, and are not likely to assume a dignity with age. But they save trouble, they establish an understanding between him who speaks and him who hears; and when they are thrown into a discourse they serve the purpose of gestures, To exclaim "I should smile" or "I should cough" is not of much help in an argument, but such interjections as these imply an appreciation not merely of slang but of your interlocutor. * To the Englishman who knows them not, the following quotations will explain their significance:-- "Tain't what ye ain't or what ye don't do that cuts ice with me." "Well, invested capital has got to protect itself when the law won't do it. Ain't them straight goods?" "Boston don't want Bishop Potter to come up here an' tell her 't she ain't next to the latest curves in goodness. Hully gee, no!"
