The world has a lot of different standards for a lot of things, but I have never heard of a place with the default screw thread direction being opposite.
So does each language have a fun mnemonic?

I’m Norwegian. I never learned a rule in my language and always just went by instinct. Until ~3rd year of university in physics where someone told me tha the right-hand-rule applies to screws. Now I use that everywhere for screws in strange positions.
