Rather be frumpy than vulgar! Much. Frumps are often celebrities in disguise -- but a person of vulgar appearance is vulgar all through.
Emily PostThe most vulgar slang is scarcely worse than the attempted elegance which those unused to good society imagine to be the evidence of cultivation.
Emily PostThe 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.
