From Chinook Jargon muckamuck (“food"). In the sense "person of authority", it is short for "high muckamuck", from Chinook Jargon hayo muckamuck (“plenty to eat, plenty of food"). See muckety muck. The ultimate source of the word is unclear; it is possible it was invented in Chinook Jargon rather than taken into the jargon from another language.
