Shog-Milk
You’d have to be a scholar in Ancient American — or else six to twelve standard Terran years, and a devotee of the Aunt Asenath’s Fun-Time Beanstalk television* show to boot — to know that ‘Shog’ means ‘shoggoth.’ Yes, the future has those, now. Somebody in the 24th Century came across the concept during one of that era’s neo-archaic craze, and they thought that it’d be cool to genetically engineer actual shoggoths out of slime molds, or something. Just between you and me, people in the Gory-Twenty-Foury could get really, really weird. At least, it seems that way to their descendants, two centuries later.
