Foppington (Lord), an empty-headed coxcomb, intent only on dress and fashion. His favourite oaths, which he brings out with a drawl, are: “Strike me dumb!” “Split my windpipe!” and so on. When he loses his mistress, he consoles himself with this reflection: “Now, for my part, I think the wisest thing a man can do with an aching heart is to put on a serene countenance; for a philosophical air is the most becoming thing in the world to the face of a person
of quality.” — Sir John Vanbrugh, The Relapse (1G97).
Foppington (Lord), a young married man about town, most intent upon dress and fashion, whose whole life is consumed in the follies of play and seduction. His favourite oaths are: “Sun, burn me!” “Curse, catch me!” “Stap my breath!” “Let me blood!” “Run me through!” “Strike me stupid!” “Knock me down!” He is reckoned the king of ill court fops. — Colley Cibber, The Careless Husband (1704).
Foppington (Lord), elder brother of Tom Fashion. A selfish coxcomb, engaged to be married to Miss Hoyden, daughter of Sir Tunbelly Clumsy, to whom he is personally unknown. His brother Tom, to whom he did not behave well, resolved to outwit him; and passing himself off as Lord Foppington, got introduced to the family, and married the heiress. When his lordship appeared, he was treated as an impostor, till Tom explained his ruse; and Sir Tunbelly, being snubbed by the coxcomb, was soon brought to acquiesce in the change, and gave his hand to his new son-in-law with
cordiality. The favourite oaths of Lord Foppington are: “Strike me dumb!” “Strike me ugly!” “Stap my vitals!” “Split my windpipe!” “Rat me!” etc.; and, in speaking, his affectation to change the vowel “o” into a, as rat, nam, resalve, waurld, ardered, mauth, paund, maunth, lang, philasapher, tarture, and so on. — Sheridan, A Trip to Scarborough (1777)
