Schrodinger's bank account

A term used in Sethical's Baku Series to describe where somebody is lying that their bank account is full of paper, saying that it's empty or not.

Lil Broomstick: Ay bro not that I'm broke or anything but you could slide a couple coins my way.
Obito, strongest muthafucka in the series: You got Schrodinger's bank account. We don't know if that shit's empty or not.
