originBorrowed from Chinook Jargon muckamuck (“food”). In the sense of person of authority, it is short for high muckamuck, from Chinook Jargon hayo muckamuck (“plenty to eat, plenty of food; to eat”). See muckety muck. The ultimate source of the word is unclear; it is possible that the term originated within Chinook Jargon itself, rather than being borrowed from another language.
