I’ve recently learned the word “pupik” (Yiddish for belly button). To me, it is a funny sounding word, and vaguely familiar. Could I have heard Krusty the Clown say it on the Simpsons? None of the quote sites I found has it.
I think that my first introduction to that word was in a book by Woody Allen. (Possibly Without Feathers, although I had a few of them. Woody Allen books, not feathers. That was my nephew.)
Harlan Ellison was fond of throwing this (and other words requiring reference volumes) in his novels and stories.
Ever get a PUPID wire at a bank? Pay Upon Proper IDentification?
Looks like it might rhyme with “pubic.”
I remember a little animal in Eddings’s Belgariad named Popik (I think.) I believe he was one of the swamp critters. Does that count? 
Pronounced more like like “poopik”. From the old R&B song “I’m Your Pupik”. Might have been Smokey Robison, but I’m not sure…
Yeah I know it’s “I’m your puppet” but for some reason I’ve always heard it as “I’m your pupik”
There’s a Bob Hope[Og, forgive me for knowing this] movie wherein he pretends he can’t speak the local language. He does;however, repeat the phrase “Farfel, farfel pipik” several times.
