Stop saying "gg" or "ff" 5 minutes into the game (especially in ranked)

I just lost a ranked game, which could have been easily won, because my cho'gath mid was upset we had a sona top. Three minutes into the game, he types "gg" because our sona got first blooded.

At that time I thought, OK he's just annoyed we have a sona top.

And then it went downhill from there.

Anytime the sona died, the cho would go off on how we lost the game, how we have to ff, blah blah. I told him we can still win the game -- our bot lane (vayne and i, janna) was winning and way ahead, cho gath himself was fed and winning his mid lane against veigar, no one on their team was really that ahead.

After 15 minutes cho started a surrender vote, we all said no. And that pissed him off. So he went and hard-pushed top. At first that seemed like a good idea, since sona lost top lane...

And then we realized that he was purposely only going top, not warding, not helping out the team, just so we could lose. We literally had an open nexus, the entire enemy team is in our base, and he is still top. We begged him kindly to come help. I told him we're going to lose if he doesn't help. His response? "That's the point."

My point with this anecdote is the fact that it's not only rampant insults and flaming that plays into the toxicity of this community, but players who grieve and give up early on, thus ruining the game for four other people. Did I already tell you that was a ranked match already? The Cho was fed, he was winning his lane hard, he could've easily carried the game, but instead he ruined the game for us just because he was pissed over a non-meta pick.

DONT PLAY RANKED IF YOU'RE GOING TO BE NEGATIVE AND THROW/RUIN THE GAME FOR EVERYONE!!!!
