Origin unknown.
(American Heritage® Dictionary of the English Language, Fourth Edition)
Unknown; many unproven theories exist, all of which lack supporting evidence. Theories include that the term originated among African Americans in the US South in the early 20th century or late 19th century; that it was first used by British soldiers stationed in Palestine before 1948, based on the Hebrew הכל בסדר (hakól b'séder, "everything is O.K."); and Louisiana French or Italian provenance. Jazz historians attribute the word's coinage to Bill "Bojangles" Robinson. (Wiktionary)

  • We have a true mystery on our hands. It certainly seems like some of the expressions are crazier than others. The Native American would be from Washington state, which is way outside the bounds of where it was used. The Yiddish also seems ridiculous.
