What Counts As Offensive Language?

Now we all get toxic every now and again, so its natural to get the odd report every other month or so but can I just say the amount of reports I am getting is insane! Some games I don't even talk until the end of the game and say "gg wp" and you will still get reported for offensive language! The past few games I have got about 3 reports, only 1 of which I felt was necessary (I flipped out on a tahm kench with 5k health and could still regen without warmogs so of course I was a pissed). But every game now everyone seems to be triggered and report you no matter the reason! What does actually count as offensive language? I'm just confused :S
