shirt-sleeves (n.): 1560s, from shirt (n.) + sleeve (n.). Usually with the notion of "without a coat."
shirt-waist (n.): 1879, from shirt (n.) + waist (n.).
shirtless (adj.): c. 1600, from shirt + -less.

shit (v.): Old English scitan, from Proto-Germanic *skit- (source also of North Frisian skitj, Dutch schijten, German scheissen), from PIE *skei- "to cut, split, divide, separate" (see shed (v.)). The notion is of "separation" from the body (compare Latin excrementum, from excernere "to separate," Old English scearn "dung, muck," from scieran "to cut, shear;" see sharn). It is thus a cousin to science and conscience.

"Shit" is not an acronym. The notion that it is a recent word might be partly because it was taboo from c. 1600 and rarely appeared in print (neither Shakespeare nor the KJV has it), and even in "vulgar" publications of the late 18c. it is disguised by dashes. It drew the wrath of censors as late as 1922 ("Ulysses" and "The Enormous Room"), scandalized magazine subscribers in 1957 (a Hemingway story in "Atlantic Monthly") and was omitted from some dictionaries as recently as 1970 ("Webster's New World").

Extensive slang usage; meaning "to lie, to tease" is from 1934; that of "to disrespect" is from 1903. Shite, now a jocular or slightly euphemistic and chiefly British variant of the noun, formerly a dialectal variant, reflects the vowel in the Old English verb (compare German scheissen); the modern verb has been influenced by the noun. Shat is a humorous past tense form, not etymological, first recorded 18c. To shit bricks "be very frightened" attested by 1961. The connection between fear and involuntary defecation has generated expressions in English since 14c. (the image also is in Latin), and probably also is behind scared shitless (1936).
Alle þe filþ of his magh ['maw'] salle breste out atte his fondament for drede. ["Cursor Mundi," early 14c.]
shit (n.): Old English scitte "purging, diarrhea," from source of shit (v.). Sense of "excrement" dates from 1580s (Old English had scytel, Middle English shitel for "dung, excrement;" the usual 14c. noun seems to have been turd). Use for "obnoxious person" is since at least 1508; meaning "misfortune, trouble" is attested from 1937. Shit-faced "drunk" is 1960s student slang; shit list is from 1942. Up shit creek "in trouble" is from 1937 (compare salt river). To not give a shit "not care" is from 1922. Pessimistic expression Same shit different day attested by 1989. Shitticism is Robert Frost's word for scatological writing.
The expression [the shit hits the fan] is related to, and may well derive from, an old joke. A man in a crowded bar needed to defecate but couldn't find a bathroom, so he went upstairs and used a hole in the floor. Returning, he found everyone had gone except the bartender, who was cowering behind the bar. When the man asked what had happened, the bartender replied, 'Where were you when the shit hit the fan?' [Hugh Rawson, "Wicked Words," 1989]

Originally used for padding, English manufacturers began making coarse wearing clothes from it, and when new it looked like broad-cloth but the gloss quickly wore off, giving the stuff a bad reputation as a cheat. The 1860 U.S. census of manufactures notes import of more than 6 million pounds of it, which was "much used in the manufacture of army and navy cloths and blankets in the United States" according to an 1865 government report.
The Days of Shoddy, as the reader will readily anticipate, are the opening months of the present war, at which time the opprobrious name first came into general use as a designation for swindling and humbug of every character; and nothing more need be said to indicate the scope of this novel.
