football (n.) Look up football at Dictionary.com
open-air game involving kicking a ball, c. 1400; in reference to the inflated ball used in the game, mid-14c. ("Þe heued fro þe body went, Als it were a foteballe," Octavian I manuscript, c. 1350), from foot (n.) + ball (n.1). Forbidden in a Scottish statute of 1424. One of Shakespeare's insults is "you base foot-ball player" [Lear I.iv]. Ball-kicking games date back to the Roman legions, at least, but the sport seems first to have risen to a national obsession in England, c. 1630. Figurative sense of "something idly kicked around, something subject to hard use and many vicissitudes" is by 1530s.

Rules of the game first regularized at Cambridge, 1848; soccer (q.v.) split off in 1863. The U.S. style (known to some in England as "stop-start rugby with padding") evolved gradually 19c.; the first true collegiate game is considered to have been played Nov. 6, 1869, between Princeton and Rutgers, at Rutgers, but the rules there were more like soccer. A rematch at Princeton Nov. 13, with the home team's rules, was true U.S. football. Both were described as foot-ball at Princeton.
Then twenty-five of the best players in college were sent up to Brunswick to combat with the Rutgers boys. Their peculiar way of playing this game proved to Princeton an insurmountable difficulty; .... Two weeks later Rutgers sent down the same twenty-five, and on the Princeton grounds, November 13th, Nassau played her game; the result was joyous, and entirely obliterated the stigma of the previous defeat.

The new and exquisitely beautiful theatre of Drury-lane has the peculiar contrivance of an iron-curtain to secure the audience from all danger, in case of fire on the stage. Miss Farren, in the occasional epilogue, delivered on opening this new theatre, pleasantly informs the spectators that, should flames burst out in the part appropriated to the representation, they may comfort themselves with thinking that nothing can be burnt but the scenery and the actors. ["The Monthly Review," June 1794]
From 1819 in the figurative sense "impenetrable barrier." In reference to the Soviet occupation of Eastern Europe, famously coined by Winston Churchill March 5, 1946, in speech at Westminster College, Fulton, Missouri, but it had been used earlier in this context (for example by U.S. bureaucrat Allen W. Dulles at a meeting of the Council on Foreign Relations, Dec. 3, 1945). The phrase had been used in the sense of "barrier at the edge of the sphere of influence of the Soviet Union" from 1920. During World War II, Goebbels used it in German (ein eiserner Vorhang) in the same sense. But its popular use in the U.S. dates from Churchill's speech.

toga (n.) Look up toga at Dictionary.com
c. 1600, from Latin toga "cloak or mantle," from PIE *tog-a- "covering," from root *(s)teg- "to cover" (see stegosaurus). The outer garment of a Roman citizen in time of peace.
The toga as the Roman national dress was allowed to be worn by free citizens only. A stranger not in full possession of the rights of a Roman citizen could not venture to appear in it. Even banished Romans were in imperial times precluded from wearing it. The appearance in public in a foreign dress was considered as contempt of the majesty of the Roman people. Even boys appeared in the toga, called, owing to the purple edge attached to it (a custom adopted from the Etruscans) toga praetexta. On completing his sixteenth, afterward his fifteenth, year (tirocinium fori), the boy exchanged the toga praetexta for the toga virilis, pura, or libera--a white cloak without the purple edge. Roman ladies (for these also wore the toga) abandoned the purple edge on being married. [Guhl & Koner, "The Life of the Greeks and Romans," transl. Francis Hueffer, 1876]
Breeches, like the word for them (Latin bracae) were alien to the Romans, being the dress of Persians, Germans, and Gauls, so that bracatus "wearing breeches" was a term in Roman geography meaning "north of the Alps."

boll (n.) Look up boll at Dictionary.com
Old English bolla "bowl, cup, pot," merged with Middle Dutch bolle "round object," borrowed 13c., both from Proto-Germanic *bul-, from PIE *bhel- (2) "to blow, inflate, swell" (see bole). Influenced in meaning by Latin bulla "bubble, ball," ultimately from the same PIE root. Extended c. 1500 to "round seed pod of flax or cotton." Boll weevil is 1895, American English.
In south Texas, among Spanish-speaking people, the insect is generally known as the 'picudo,' a descriptive name which refers to the snout or beak of the insect. English-speaking planters generally referred to the insect at first as 'the sharpshooter,' a term which for many years has been applied to any insect which causes through its punctures the shedding of the squares or the rotting of the bolls. As there are several native insects that are commonly called sharpshooters and which, though injurious, are by no means to be compared with this insect, it becomes necessary to discourage in every way the use of the word sharpshooter as applied to this weevil. The adoption of the term 'Mexican cotton-boll weevil' for the new pest is recommended.

shebang (n.) Look up shebang at Dictionary.com
1862, "hut, shed, shelter," popularized among soldiers in the U.S. Civil War, but like other Civil War slang (such as skedaddle) of uncertain origin. Perhaps an alteration of shebeen (q.v.), but shebang in the sense "tavern," a seemingly necessary transitional sense, is not attested before 1878 and shebeen seems to have been not much used in the U.S. Bartlett's 1877 edition describes it as "A strange word that had its origin during the late civil war. It is applied alike to a room, a shop, or a hut, a tent, a cabin; an engine house." Phrase the whole shebang first recorded 1869, but relation to the earlier use of the word is obscure. Either or both senses also might be mangled pronunciations of French char-à-banc, a bus-like wagon with many seats. For an older guess:
[Shebang] used even yet by students of Yale College and elsewhere to designate their rooms, or a theatrical or other performance in a public hall, has its origin probably in a corruption of the French cabane, a hut, familiar to the troops that came from Louisiana, and constantly used in the Confederate camp for the simple huts, which they built with such alacrity and skill for their winter quarters. The constant intercourse between the outposts soon made the term familiar to the Federal army also.

trivia (n.) Look up trivia at Dictionary.com
"trivialities, bits of information of little consequence," by 1932, from the title of a popular book by U.S.-born British aphorist Logan Pearsall Smith (1865-1946) first published in 1902 but popularized in 1918 (with "More Trivia" following in 1921 and a collected edition including both in 1933), containing short essays often tied to observation of small things and commonplace moments. Trivia is Latin, plural of trivium "place where three roads meet;" in transferred use, "an open place, a public place." The adjectival form of this, trivialis, meant "public," hence "common, commonplace" (see trivial). The Romans also had trivius dea, the "goddess of three ways," another name for Hecate, perhaps originally in her triple aspect (Selene/Diana/Proserpine), but also as the especial divinity of crossroads (Virgil has "Nocturnisque hecate triviis ululata per urbes"). John Gay took this arbitrarily as the name of a goddess of streets and roads for his mock Georgic "Trivia: Or, the Art of Walking the Streets of London" (1716); Smith writes in his autobiography that he got the title from Gay.
I KNOW too much; I have stuffed too many of the facts of History and Science into my intellectuals. My eyes have grown dim over books; believing in geological periods, cave dwellers, Chinese Dynasties, and the fixed stars has prematurely aged me. ["Trivia," 1918 edition]
Then noted c. 1965 as an informal fad game among college students wherein one asked questions about useless bits of information from popular culture ("What was Donald Duck's address?") and others vied to answer first.
Nobody really wins in this game which concentrates on sports, comics and television. Everyone knows that Amos's wife on the "Amos 'n' Andy Show" is Ruby, but who knows that she is from Marietta, Georgia? Trivia players do. They also know the fourth man in the infield of Tinker-to-Evers-to-Chance, the Canadian who shot down Baron Von Richtofen, and can name ten Hardy Boy books. ["Princeton Alumni Weekly," Nov. 9, 1965]
The board game Trivial Pursuit was released 1982 and was a craze in U.S. for several years thereafter.
