Someone didn’t go to PC cafés with 20+ friends to play Dota and CS after school and yell profanities left, right and center and it shows! And don’t worry, they’re also insulting each other, lol.

But honestly, if you can’t handle people getting spicy and being overtaken by their emotions sometimes, just mute them. I did that with LoL (and I also muted myself not to be a troublemaker cause I used to get verbally abusive…) back when I played.
