The etymology of the word is not generally agreed upon. The Merriam-Webster Dictionary says it is based on the German Scheißer (literally "shitter" but also used to refer to deceivers), but the Oxford English Dictionary describes it as "of obscure origin", possibly deriving from a historical sense of "shy" meaning disreputable. Various false etymologies have suggested an anti-Semitic origin, possibly associated with the character of Shylock from Shakespeare's Merchant of Venice, but there is no clear evidence for this. One source claims that the term originated in Philadelphia in 1843 from a disreputable attorney named "Schuster."
