A mucky-muck is anyone wearing slacks on the construction site. Or any other form of business that normally don't have people wearing suit slacks. Example; architects, project managers, owners.

A pompous person of importance (often of imagined and real power). From the phrase "High Muck-a-Muck", itself descended from Chinook Jargon, a pidgin language combining words from English, French, and several Pacific Northwest Native American languages.

Your boss. Over paid, under worked. All perks, no work. The guy who wears flip-flops to work when you wear steel-toed boots.
