mud (n.)

late 14c., mudde, "moist, soft earth," cognate with and probably from Middle Low German mudde, Middle Dutch modde "thick mud," from Proto-Germanic *mud- from PIE *(s)meu-/*mu- [Buck], found in many words denoting "wet" or "dirty" (source also of Greek mydos "damp, moisture," Old Irish muad "cloud," Polish muł "slime," Sanskrit mutra- "urine," Avestan muthra- "excrement, filth"); related to German Schmutz "dirt," which also is used for "mud" in roads, etc., to avoid dreck, which originally meant "excrement." Welsh mwd is from English. The older word is fen.

Meaning "lowest or worst of anything" is from 1580s. As a word for "coffee," it is hobo slang from 1925; as a word for "opium" from 1922. Mud-puppy "salamander" is by 1855, American English; the mud-dauber wasp was so called by 1856. The children's mud-pie is attested from 1788. Mud-flat "muddy, low-lying ground near a shore" is by 1779. Mud-room "room for removing wet or muddy footwear" is by 1938.

The expression clear as mud (that is, "not clear at all") is by 1796. To throw or hurl mud "make disgraceful accusations" is from 1762. To say (one's) name is mud and mean "(one) is discredited" is recorded from 1823, from mud in obsolete sense of "a stupid twaddling fellow" (1708). Mud in your eye as a toast is recorded from 1912, American English.

defile (v.)

c. 1400, "to desecrate, profane;" mid-15c., "to make foul or dirty," also "to rape, deflower," alteration of earlier defoulen, from Old French defouler "trample down, violate," also "ill-treat, dishonor," from de- "down" (see de-) + foler "to tread," from Latin fullo "person who cleans and thickens cloth by stamping on it" (see foil (v.1)).

The alteration (or re-formation) in English is from influence of Middle English filen (v.) "to render foul; make unclean or impure," literal and figurative, from Old English fylen (trans.), related to Old English fulian (intrans.) "to become foul, rot," from the source of foul (adj.). Compare befoul, which also had a parallel form befilen. Related: Defiled; defiling.

twerk (v.)

"to dance in a way that simulates the body's action in copulation," by 2005, alteration of twurk, which seems to have originated in the Atlanta, Georgia, strip club and hip-hop scene and first came to wide attention in the Ying Yang Twins' 2000 song "Whistle While You Twurk," described as "an ode to strippers" ["Country Fried Soul, Adventures in Dirty South Hip-Hop"]. Probably ultimately imitative of something. Related: Twerked; twerking. There is a verb twirk from 1599, "to pull, tug, twirl," what a man does with his mustache, but OED regards this as possibly a misprint of twirl.

ragamuffin (n.)

mid-14c., "demon;" late 14c., "a ragged lout," also in surnames (Isabella Ragamuffyn, 1344), from Middle English raggi "ragged" ("rag-y"?) + "fanciful ending" [OED], or else perhaps second the element is Middle Dutch muffe "mitten." Or, as Johnson has it, "From rag and I know not what else."

Ragged was used of the devil from c. 1300 in reference to his "shaggy" appearance. Raggeman (late 13c. as a surname, presumably "one who goes about in tattered clothes") was used by Langland as the name of a demon (late 14c.), and compare Old French Ragamoffyn, name of a demon in a mystery play. Sense of "dirty, disreputable boy" is from 1580s. Also compare ragabash "idle, worthless fellow" (c. 1600).

mollycoddle (v.)

also molly-coddle, by 1839 (implied in mollycoddling), from a noun (by 1828) meaning "overly pampered, fastidious, effeminate male," from Molly (pet name formation from Mary), which had been used contemptuously at least since 1707 for "a milksop, an effeminate man" (see molly (n.1)) + coddle (q.v.). Related: Mollycoddled.

All his pursuits had been sedentary; for he never went out but with his mother. He was not allowed to stroll about the farm with his father, lest he should get his clothes dirty and his feet wet. In short, he was what Giles Darman pronounced him to be—"a little mollycoddle." ["Babbington Droneham," Hood's Magazine, March 1844]

limerick (n.)

type of nonsense verse of five lines, 1896, perhaps from the county and city of Limerick in Ireland, but if so the connection is obscure. Often (after OED's Murray) attributed to a party game in which each guest in turn made up a nonsense verse and all sang a refrain with the line "Will you come up to Limerick?" but he reported this in 1898 and earlier evidence is wanting. Or perhaps from Learic, from Edward Lear (1812-1888) English humorist who popularized the form. Earliest examples are in French, which further complicates the quest for the origin. OED's first record of the word is in a letter of Aubrey Beardsley.

The limerick may be the only traditional form in English not borrowed from the poetry of another language. ... John Ciardi suggests that the Irish Brigade, which served in France for most of the eighteenth century, might have taken the form to France or developed an English version of a French form. ... The contemporary limerick usually depends on a pun or some other turn of wit. It is also likely to be somewhat suggestive or downright dirty. [Miller Williams, "Patterns of Poetry," Baton Rouge: Louisiana State University, 1986]

The place name is literally "bare ground," from Irish Liumneach, from lom "bare, thin." It was famous for hooks.

bouncer (n.)

1762, "one who bounces," agent noun from bounce (v.), which originally meant "to thump, hit." Given various specific senses in 19c., such as "boaster, bully, braggart" (1833); also "large example of its kind" (1842); "enforcer of order in a bar or saloon" (1865, American English, originally colloquial).

Now it so happened that the brakeman was what is known, in the language of the road, as a "bouncer." That is, he was a hybrid combining the qualities of a brakeman and a bruiser, and was frequently called into requisition by the conductor to take the dirty work of ejecting tramps off of his hands. ["Staats," "A Tight Squeeze," 1879]
"The Bouncer" is merely the English "chucker out". When liberty verges on license and gaiety on wanton delirium, the Bouncer selects the gayest of the gay, and — bounces him! [London Daily News, July 26, 1883]

logogram (n.)

"word-sign, sign or character representing a word," 1840, from logo- "word" + -gram. Generically, "any symbol representing graphically a product, idea, etc.," from 1966. The earliest use of the word (1820) is in the sense "logograph," but OED explains this as a substitute for logograph, "which in this sense is itself a mistake for logogriph," the old type of word-puzzle.
