What is the definition of Naturals Macabre?

"Naturals macabre is a delightfully morbid combination of 'natural' and 'acabre,' like saying a sunflower is a horror movie villain with an over-sized skeleton tucked inside. It's the art of finding the spooky in the utterly ordinary, so much so it makes your skin crawl while simultaneously making your heart flutter at the same time."

Example sentence: "Despite being a well-known horror flick, the creepy old mansion was actually just a vintage flower shop with an overgrown garden, proving that 'naturals macabre' isn't just for ghost hunters."
