What is the definition of Notify Macabre?

"Notify macabre" is like giving the universe a high-five after it's played a particularly gruesome prank on you. It's a fancy way of saying to tell someone that you've been doused in paint, or worse, that they've witnessed a ghost in the closet that's as creepy as a bad hair day.

Here's an unsettling example sentence: "After the creepy neighbor's haunted house tour, I decided to notify macabre - my cat just found out the real reason it's been purring like a cork."
