**Just stop**. It's never been a good excuse, it isn't and it most probably never will be. And I see it a lot lately.
Sure, we are human, we have emotions. It's completely normal and OK to get angry when the game's not going well. But it's **not **OK to yell at your teammates because of it.
By the same logic, it should be perfectly fine to kill the neighbor's dog just because he annoys you with barking. Because it's natural to get angry, right?
**Self control**, people. You need to look into it.
