George bumped into an old acquaintance who had once made fun of him. Learning that the recovering alcoholic was now apologizing to people he’d hurt, George waited for his like a man who knows that Publisher’s Clearing House is headed to his house. When George’s “jackpot” turned “crackpot”–making even more fun of George–George got a little riled up. (And this was him giving Jerry the lowdown.)
So someone called you a name. Call them out with this line–loudly, hitting those syllables like you’re banging drums. The allusion to jazz music will have you saying several possible things about that jokester’s punchline–one of which is, no one gets it. And you don’t have to be a conversational “musician” to know a well-played number when you hear it, so if there is something to get in what they said, then you’re saying this about their “jazz”: it ain’t all that.
