crystal: [OE] The prehistoric Indo-European base *kru- produced several words denoting ‘hard outer surface’, including English crust, Old High German hrosa ‘crust’, and Old Norse hrúthr ‘crust’. In some cases they reflect a hardening caused by freezing: Old High German hrosa, for example, also meant ‘ice’, and Greek krúos meant ‘frost’.

From this was derived krustaímein ‘freeze’, which in turn formed the basis of krústallos ‘ice’. When Old English first acquired the word, via Latin crystallum and Old French cristal, it still meant ‘ice’, a sense which survived until the 16th century, although losing ground all the time to the metaphorical extension ‘clear mineral’.

doodle (v.)youdaoicibaDictYouDict
"scrawl aimlessly," 1935, from dialectal doodle, dudle "fritter away time, trifle," or associated with dawdle. It was a noun meaning "simple fellow" from 1620s.
LONGFELLOW: That's a name we made up back home for people who make foolish designs on paper when they're thinking. It's called doodling. Almost everybody's a doodler. Did you ever see a scratch pad in a telephone booth? People draw the most idiotic pictures when they're thinking. Dr. Von Holler, here, could probably think up a long name for it, because he doodles all the time. ["Mr. Deeds Goes to Town," screenplay by Robert Riskin, 1936; based on "Opera Hat," serialized in "American Magazine" beginning May 1935, by Clarence Aldington Kelland]
Related: Doodled; Doodling.

evermore (adv.)youdaoicibaDictYouDict
c. 1300 as one word, "at all times; all the time; forever, eternally;" see ever + more. Replacing evermo (13c.), from Old English æfre ma.
mutt (n.)youdaoicibaDictYouDict
1901, "stupid or foolish person," probably a shortening of muttonhead (1803) in the same sense; see mutton and compare meathead, etc. Mutt was used by 1898 of a dog, especially a stupid one, and perhaps this is the same word formed independently (muttonhead also was used of stupid animals), or else a separate word of unknown derivation. Wright's "English Dialect Dictionary" (1900) has "Mutton! used in scolding a dog, prob. in allusion to the offence of sheep-worrying."
"That dog ain't no mutt," McManus would say as he stood behind the bar opening oysters; "no an he ain't no rube! Say! he's in it all the time when Charley trims the steaks." [Robert W. Chambers, "The Haunts of Men," 1898]
Used by 1910 in dog fancier publications to refer to a non-purebred animal.
punk (n.2)youdaoicibaDictYouDict
"worthless person" (especially a young hoodlum), 1917, probably from punk kid "criminal's apprentice," underworld slang first attested 1904 (with overtones of "catamite"). Ultimately from punk (n.1) or else from punk "prostitute, harlot, strumpet," first recorded 1590s, of unknown origin.

For sense shift from "harlot" to "homosexual," compare gay. By 1923 used generally for "young boy, inexperienced person" (originally in show business, as in punk day, circus slang from 1930, "day when children are admitted free"). The verb meaning "to back out of" is from 1920.

The "young criminal" sense is no doubt the inspiration in punk rock first attested 1971 (in a Dave Marsh article in "Creem," referring to Rudi "Question Mark" Martinez); popularized 1976.
If you looked different, people tried to intimidate you all the time. It was the same kind of crap you had to put up with as a hippie, when people started growing long hair. Only now it was the guys with the long hair yelling at you. You think they would have learned something. I had this extreme parrot red hair and I got hassled so much I carried a sign that said "FUCK YOU ASSHOLE." I got so tired of yelling it, I would just hold up the sign. [Bobby Startup, Philadelphia punk DJ, "Philadelphia Weekly," Oct. 10, 2001]
tank (v.)youdaoicibaDictYouDict
1900, "to put into a tank," from tank (n.). Meaning "to lose or fail" attested from 1976, originally in tennis jargon, specifically in an interview with Billie Jean King in "Life" magazine, Sept. 22, 1967:
"When our men don't feel like trying," she says, "They 'tank' [give up]. I never tanked a match in my life and I never saw a girl do it. The men do it all the time in minor tournaments when they don't feel like hustling. You have to be horribly competitive to win in big-time tennis."
Sometimes said to be from boxing, in some sense, perhaps from the notion of "taking a dive," but evidence for this is wanting. Related: Tanked; tanking. Adjective tanked "drunk" is from 1893.
