1737, "a medicine which excites vomiting;" 1966 as "material thrown up in vomiting," from puke (v.). U.S. colloquial meaning "native of Missouri" (1835) might be a different word, of unknown origin.

It is well known, that the inhabitants of the several western States are called by certain nicknames. Those of Michigan are called wolverines; of Indiana, hooshers; of Illinois, suckers; of Ohio, buckeyes; of Kentucky, corn-crackers; of Missouri pukes, &c. To call a person by his right nickname, is always taken in good part, and gives no offence; but nothing is more offensive than to mis-nickname—that is, were you to call a hoosher a wolverine, his blood would be up in a moment, and he would immediately show fight. [A.A. Parker, "Trip to the West and Texas," Concord, N.H., 1835]

Bartlett (1859) has "A nickname for a native of Missouri" as the second sense of puke (n.), the first being "A mean, contemptible fellow." The association of the state nickname with the "vomit" word is from at least 1858, and folk etymology talks of the old state literally vomiting forth immigrants to California.

annual awards for distinguished work in U.S. journalism, letters, music, etc., 1918, named for U.S. journalist Joseph Pulitzer (1847-1911), publisher of the New York Globe, who established the awards in 1917 through an endowment to Columbia University.

c. 1300, "to move forcibly by pulling, to drag," from Old English pullian "to pluck off (wool), to draw out," of unknown origin, perhaps related to Low German pulen "remove the shell or husk," Frisian pûlje "to shell, husk," Middle Dutch polen "to peel, strip," Icelandic pula "work hard." Related: Pulled; pulling.

Early 14c. as "to pick, pull off, gather" (fruit, flowers, berries, leaves, petals, etc.); mid-14c. as "to uproot, pull up" (of teeth, weeds, etc.). Sense of "to draw (to oneself), attract" is from c. 1400; sense of "to pluck at with the fingers" is from c. 1400; meaning "tear to pieces" is mid-15c. By late 16c. it had replaced draw (v.) in these senses. Common in slang 19c.-20c.; Bartlett (1859) has to pull foot "walk fast; run;" pull it "to run." To pull up "check a course of action" is from 1808, figurative of the lifting of the reins in horse-riding.

To pull (someone's) chain in figurative sense is from 1974, perhaps on the notion of a captive animal; the expression was also used for "to contact" (someone), on the notion of the chain that operates a signaling mechanism. To pull (someone's) leg is from 1882, perhaps on notion of "playfully tripping" (compare pull the long bow "exaggerate," 1830, and pulling someone's leg also sometimes was described as a way to awaken a sleeping person in a railway compartment, ship's berth, etc.). Thornton's "American Glossary" (1912) has pull (n.) "a jest" (to have a pull at (someone)), which it identifies as "local" and illustrates with an example from the Massachusetts "Spy" of May 21, 1817, which identifies it as "a Georgian phrase." To pull (one's) punches is from 1920 in pugilism, from 1921 figuratively.

To pull in "arrive" (1892) and pull out "depart" (1868) are from the railroads. To pull (something) off "accomplish, succeed at" is originally in sporting, "to win the prize money" (1870). To pull (something) on (someone) is from 1916; to pull (something) out of one's ass is Army slang from 1970s. To pull rank is from 1919; to pull the rug from under (someone) figuratively is from 1946.

sleeping car on a passenger train, 1867, Pullman car, in recognition of U.S. inventor George M. Pullman (1831-1897) of Chicago, who designed a railroad car with folding berths.

The Pullman Sleeping Car.—"The Western World." This splendid specimen of car architecture, being one of a number of sleeping-cars to be completed for the Michigan Central road, by Mr. Pullman, has created a great sensation among railway circles east. ... The car itself is admitted by all who have seen it to be, in the matter of sleeping and cooking accessories, and superb finish, the ne plus ultra of perfection. Nothing before has been seen to equal, much less surpass it. [Western Railroad Gazette, Chicago, quoted in Appleton's Illustrated Railway and Steam Navigation Guide, New York, June, 1867]
