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’ve always thought this too. I understand clockwise/anticlockwise and the direction being defined from the top - but it’s a circle - no matter which way you turn, it spends 50% of the time going either direction. The phrase works with screwdrivers (especially ratcheting ones), but not so much spanners or Hex Keys IMO.
I always railed against this. I’m using clockwise-lockwise from now on.
