I vaguely recall an instance where a Fremen insults someone by indicating that they are so terrible it would be no loss if that person died and their body's water was not reclaimed. I've only read Dune and Dune Messiah, so I imagine the insult was found in one of those, but I don't have a copy of either accessible and can't find any evidence of such a quote online. This has led me to believe that I may have just come up with the insult myself and forgotten it was never in the books.
The version of this insult floating around my head is "I hope your water is wasted," but the actual quote (if it exists) may be nothing like that.
Was there any instance of a Fremen using such an insult in Dune or Dune Messiah? If not, did any character use that insult in those books, or anywhere else in the Dune saga?
