Depends where you live, it’s somehow still alive and well in Poland! You’d usually use the lowercase xd for a more refined and low-key vibe tho, the full caps ones are reserved for special occasions.

Arbitrarily forcing a choice to clarify your feelings on the matter can actually be very useful, it’s just a bit rude to use other people for it. When I have a choice like this I’ll sometimes throw some dice (d6, 1-3 for white, 4-6 for blue), if I’m happy or don’t mind what they landed on then it’s the correct choice, if I’m not I’ll probably realize which option I was secretly hoping for and go with that.
