What is the definition of Cassette Blood Cells?

"Cassette blood cells" is like a bizarre mix-up in the medical world, where your regular blood cells get stuck inside an old cassette tape, hence the name. It's a term that sounds like it comes straight from a sci-fi horror movie, but it's actually just a quirky medical term. Think of it as when your favorite band gets stuck on a recording, but instead of a song, it's your body's own blood cells trapped in a vinyl prison.

Now, here's an unsettling example sentence: "The detective's cassette blood cell analysis suggested the culprit was a blood type mismatch with the victim's, but then he decided to double-check for 'cassette blood cells' in the case files before he let anyone in."
