Yup.
You were flaming, calling names, making fun of your team mates, sarcasm...
Try not flaming anyone next time, thats the main reason people lose their games. You start focusing on what everyone does instead your own game + you make everyone else focus on what to respond and your mistakes aswell, at the end no one is a perfect gamer.
Focus on your game without flaming and you'll have more chances to win

Do you realize that calling out all the mistakes of everyone is useless? What done is done.
