And yes, if you want a dependably straight answer, do cross off Urban Dictionary from your list.

Not my list, Google's list.

My point remains that the word isn't in wide use here so your wit was lost on me.

They left an S off the author's last name.

As you might accordingly surmise, "Crisco" would be almost de rigueur as a Yank's eggcorn for both "Kisco" and "Cristo".

Aw, c'mon; you can say it. Around these parts some say "Varnish". I like your "Vanish" better, though; then you could call the tune "The Mohel" . But I call it "The Spanish Misfortune"; got that from a kid who misheard me. I like it; it sounds like a venereal pox. Then there's "The Chinese Chickens", which was an actual mishearing on my own part .

At a session I once launched into what I announced as "Montezuma's Revenge". "Montezuma's Revenge?" they cried; "But that's The Stool of Repentance!" "Think about it," said I.

I love mangled tune names; I've probably got a million of 'em. I will be eternally grateful to the green young fellow who pronounced "The Kesh" as "The Quiche".

"The Flying Toad"? I'm drawing a blank.

I honestly didn't think my point was all that subtle, but maybe I've outdone myself unawares.

So the word "dumbass" has little currency in your vernacular, then? Is that it?

Why so cryptic?

Does your pronunciation of 'Dumas' lead to homophony?

I love the Montezuma's Revenge, lol.

FWIW, I read you loud and clear...

(Though it may be due to the fact that I sometimes pronounce that word that way for funsies.)

The eggcorn doesn't fall very far from the tree, does it?
