schmoo (n.)youdaoicibaDictYouDict
fabulous animal, ready to fulfill man's wants, 1948, invented by U.S. cartoonist Al Capp (Alfred Caplin, 1909-1979); the name perhaps based on schmoe.
schmooze (v.)youdaoicibaDictYouDict
also shmooze, "to chat intimately," 1897, from Yiddish shmuesn "to chat," from shmues "idle talk, chat," from Hebrew shemu'oth "news, rumors." As a noun from 1939. Related: Schmoozed; schmoozing. Schmoozer is from 1909.
schmuck (n.)youdaoicibaDictYouDict
also shmuck, "contemptible person," 1892, from East Yiddish shmok, literally "penis," probably from Old Polish smok "grass snake, dragon," and likely not the same word as German Schmuck "jewelry, adornments," which is related to Low German smuck "supple, tidy, trim, elegant," and to Old Norse smjuga "slip, step through" (see smock).

In Jewish homes, the word was "regarded as so vulgar as to be taboo" [Leo Rosten, "The Joys of Yiddish," 1968] and Lenny Bruce wrote that saying it on stage got him arrested on the West Coast "by a Yiddish undercover agent who had been placed in the club several nights running to determine if my use of Yiddish terms was a cover for profanity." Euphemized as schmoe, which was the source of Al Capp's cartoon strip creature the shmoo.

"[A]dditional associative effects from German schmuck 'jewels, decoration' cannot be excluded (cross-linguistically commonplace slang: cf. Eng. 'family jewels')" [Mark R.V. Southern, "Contagious Couplings: Transmission of Expressives in Yiddish Echo Phrases," 2005]. But the English phrase refers to the testicles and is a play on words, the "family" element being the essential ones. Words for "decoration" seem not to be among the productive sources of European "penis" slang terms.
schnapps (n.)youdaoicibaDictYouDict
1818, kind of Holland gin, from German Schnaps, literally "a mouthful, gulp," from Low German snaps, from snappen "to snap" (see snap (v.)). For sense, compare nip for "alcoholic drink quickly taken."
schnauzer (n.)youdaoicibaDictYouDict

schnitzel (n.)youdaoicibaDictYouDict
veal cutlet, 1854, from German Schnitzel "cutlet," literally "a slice," with -el, diminutive suffix + Schnitz "a cut, slice" (+ -el, diminutive suffix), from schnitzen "to carve," frequentative of schneiden "to cut," from Old High German snidan, cognate with Old English sniþan "to cut," from Proto-Germanic *snitt-ja-, from PIE root *sneit- "to cut."
schnook (n.)youdaoicibaDictYouDict
1948, probably from Yiddish shnuk "elephant's trunk," or altered from schmuck (q.v.), or perhaps from German schnucke "a small sheep," used in U.S. Yiddish for "a customer easily persuaded, a sucker."
schnorrer (n.)youdaoicibaDictYouDict
1892, from Yiddish, "beggar," from German slang schnurrer, from schnurren "to go begging" (slang), perhaps ultimately imitative of the sound of pleading or whining (compare sneer, snorkel, snarl).
