What is the definition of Xerox Blood Cells?

"Xerox blood cells" are like the superheroes of biotechnology who come to life every time you hear about them. They're basically a cross between a photocopying machine and a medical marvel, capable of replicating blood cells in a matter of seconds, saving countless lives. But here's the kicker - they're so lifelike, they might just start asking for superhero salads!

Example sentence: "When the hospital announced their new blood bank could only run out of 'xerox blood cells,' the doctors just laughed and said, 'Just remember, they're not really from another world, but they sure look like it!'"
