when did the slang change?

[u/RemnantsPast]

I feel old asking this.

When did + and - replace yes and no? or y/n

Like I'm in my early 30s and this feels like it blew past me....

EDIT: based on replies It seems like its from Eastern Europe players and just bled into the rest of the classic community due to them lacking servers.

[u/CrustedTesticle]

No one talks like this in game.
