In the movie “League of Extraordinary Gentlemen” it was said (contemptuously):
“How many times do I have to kill these Chritons?”
I am only finding “positive” words such as:
Kriton: Name means you have clever mind, good business judgement, sense of responsibility and an appreciation of the finer things of life.
Chreighton: Name is probably an early hybrid compound of Old Welsh creic (rock) and Older Scots tun (farm, settlement).
Only Kryten I had heard mentioned before was the droid in “Red Dwarf” series.
