Tangential, but I would be curious to know if "capiche" refers to the Italian "capisci?", which is Neapolitan dialect meaning "do you understand?".

You might as well not ask him for no free s___, capiche?
Google tells me it’s “from Italian capisce third person singular present tense of capire ‘understand’”
When you say "capisc?", instead of "capisce?" (written: capisci?), Italians mostly feel that the word is said following a southern Italian dialect.
