I'm still surprised by the french translation of "mob". It's not a thousands of people, it's just some kind of animal...
The Term MOB originated in Developer Talk, as far as I know. It stands for: Mobile OBject
A digital object/entity that is not at a fixed place in the Game and moves around. An “Animal NPC” if you wish. ;)
To add to the list:
I myself am always a bit amused when DeepL translates “Homin” coming from a French Player to German as “Homo”. Which is deprecative slang for a male gay person.
