“Skookumchuck” describes turbulent water or rapids, such as those in a steam or river. It’s not widely used anymore, but most folks in the PNW are at least familiar with it (sometimes from the names of places or people), and it’s the only place you’ll hear the term in America. (For the record, it is also used in British Columbia.)
Shazam, Pilgrims! Ah’s always reckon’d it be de sound yer makes after yer ett too much rancid Spam an’ Tang.
My understanding is that Skookum (strong) and Chuck (water) are from a pidgin language used to trade with Native Americans in the pacific Northwest. As such, it really would only be valid for that area. Other areas haven’t historically used the term.
FE has probably been snowed in and rations ran low. That’s when you get creative and eat Spam sandwiches, Vienna sausages and pickled eggs.
Just writing that made my stomach grumble.
