Portrait of H. L. Mencken H. L. Mencken The American Language — Expletives and Forbidden Words (1919)

When we come to words that, either intrinsically or by usage, are improper, a great many curious differences between English and American reveal themselves. The Englishman, on the whole, is more plain-spoken than the American, and such terms as bitch, mare and on foal do not commonly daunt him, largely, perhaps, because of his greater familiarity with country life; but he has a formidable index of his own, and it includes such essentially harmless words as sick, stomach, bum and bug. The English use of ill for sick I have already noticed, and the reasons for the English avoidance of bum.

Portrait of H. L. Mencken H. L. Mencken The American Language — Expletives and Forbidden Words (1919)

In their vocabularies of opprobrium and profanity English and Americans diverge sharply. The English mucker, rotter and blighter are practically unknown in America, and there are various American equivalents that are never heart in England. A guy, in the American vulgate, simply signifies a man; there is not necessarily any disparaging significance. But in English, high or low, it means one who is making a spectacle of himself.
