What is the definition of Reserves Macabre?

"A 'eserves macabre' is like having a closet full of old horror movie memorabilia, but instead of just being nostalgic, you're secretly terrified by the potential for actual gore. It's the kind of thing where you can't help but laugh at your own morbid fascination with death, but can't quite shake the feeling that it's just a really bad costume party gone wrong."

Edgy example sentence: "I think the reserves macabre in my closet were better filled with actual haunting experiences than with overpriced Halloween costumes."
