Emily Post - The fact that slang is apt and forceful makes its use irresistibly tempting

The fact that slang is apt and forceful makes its use irresistibly tempting. Coarse or profane slang is beside the mark, but "flivver," "taxi," the "movies," "deadly" (meaning dull), "feeling fit," "feeling blue," "grafter," a "fake," "grouch," "hunch" and "right o!" are typical of words that it would make our spoken language stilted to exclude.
