When the enemy carry comes and kills you for picking on their support.

I actually did this yesterday with Teemo. They went after Soraka and I told them they'll pay. Killed three of them thanks to their low health and my AP. Told them they paid the price for killing a support. I don't play Teemo just for fun. >:) I play him to get revenge in the game. To mock the enemy team! That is the code of Teemo! :3
