What is the definition of Wrote Macabre?

"Wrote macabre" is a whimsical way of saying someone penned something that's all about the spooky side of life, like a dark joke only adults would appreciate. Imagine this: "After the horror movie marathon, John decided to write macabre poetry about the existential dread of a cat purring on his lap." Sounds like something you'd find in a creepy horror anthology, but let's keep it PG-13, right?
