A twenty dollar bill.
First contrived by a man who believed that Jefferson appeared on the twenty. But as we all know Jackson is the president who face dons the twenty. We still use the term today to mock this man.
Man that date was expensive... I almost had to drop an entire Jeffie.
Macdaddies employee: "That'll be $32.09 at the window"
Me: "Damn, that's over two and a half Jeffies."
