"I love you too"
This simple sentence will help you avoid flaming. No, really! Just use it whenever someone tries to pick a fight.
EX: Laner: F-------ing n00b jg never ganks me, f------ing retard. You: I love you too
ADC: WTF!! Support why didn't you peel you F-----ing peice of ------------------------- You: I love you too
Enemy laner: F-----ing (Insert league 1 below his own here) n00b, you need too use such a tryhard champ to win, f**ing %%%got You: I love you too
This might seem a little stupid but next time somebody tries to pick a fight before you go through with whatever message you just angrily smashed into your keyboard try it, it is not reportable by any means and has just enough cheeky bullshitery too get your point across.
PS if you are playing Mundo or Bard the lines "MUNDO!!, SHLURPSHLURP" or "DING DONG BWAAAAAAH!!" Are also acceptable.
