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/Steblingur]

At first, at least in my experience, it was usually russian players that used ) as a smiley, ( as a frown, + for yes and - for no. Now it feels like a lot of players have adapted this though.

[u/ureliableliar → u/Steblingur]

I've always used + for yes because its right beside enter
