shyster

• schister, scheister, sheister, schyster, shister, shaista, shiester, schiester

US origin, 19th century. The etymology of the word is not generally agreed upon. The Oxford English Dictionary describes it as "of obscure origin," possibly deriving from a historical sense of shy meaning "disreputable", equivalent to shy +‎ -ster. Other sources suggest the word derives from the German Scheißer (“incompetent worthless person”), from scheißen (“to defecate”), probably influenced by -ster. Not related to shylock.

     True, it was a good advertisement at Boosters' Club lunches, and all the varieties of Annual Banquets to which Good Fellows were invited, to speak sonorously of […] a thing called Ethics, whose nature was confusing but if you had it you were a High-class Realtor and if you hadn't you were a shyster, a piker, and a fly-by-night.
