I usually only say gg if I play with friends, or if the other person says it first and I agree with them.
Not every game is a gg? It'd be lying if I said good game every game, whether I won or lost.
Most of the time, after I start the match, I think "I'm going to do this"
If I do it, gg I could care less if I win or lose, but if I don't do it, or if I randomly break it's not a gg for me, might be for you because, you beat a custom belt yay.
Just think before saying it, or say gg? if others think it is, they'll say it back.
Or rage at you because they're a sore loser. Like pusga and manlypotato
