What is quote-on-quote?

When people who are either inept with the English language or stupid hear the phrase "quote unquote" and construe it as quote on quote.

and I repeat quote on quote, "let there be light."

I mishearing of quote, unquote when a person is usually quoting someone else’s phrase or saying something unsurely or in a sarcastic manner

Person 1: I heard that so-and-so had a quote-on-quote “illness” yesterday
Person 2: uhhh, don’tcha mean “quote, unquote?”
Person 1: sure, whatever
