What is the definition of Currency Macabre?

"Currency macabre" is like a macabre collection of cash that's as morbid as a haunted amusement park. It's the uncanny, eerie, and slightly unsettling use of money that seems to dance with the shadows, almost like it's playing hide-and-seek with death itself.
