So I'm just sitting in fountain at 11 minutes, waiting on the 20 minute mark to surrender.
Champion Select Everything's going well, no one's talking comp looks great. Last pick, picks Teemo. I jokingly say (sort of): Come on man why'd you ruin the comp @_@ Jungler (Olaf): Kill yourself (I'm not sure if he was talking me to or Teemo, Teemo tells me in game he was referring to him)

Game starts, Olaf runs straight into the enemy jungle and gives FB, botlane followed because he was being poked down and running towards botlane. After Olaf dies, so does Maoki and Jinx giving Vayne all the kills. Vayne was 5/0 by 5 minutes. Atleast 13/0 by 10.
Now, that's fine, dying. But on purpose? Olaf continously bought boots and just ran into people whether tower diving at level 3-4 or just running around them. He kept spamming his twitch link in chat and as soon as the game was over Olaf had 4 Lucidity boots and a good 15 deaths or so.
End game lobby he spams his twitch link and his Twitch title is Intentionally Feed if Disrespected.
I was demoted.
What is life.
