It's not trolling when others do it but when you do it .
today i had a game where a skarner was dancing in front of the enemy support at the beginning of the match , he was literally trolling because he knew the enemy could kill him . and that happened , i got killed too in the process .
because of that , i couldn't keep up with my adc and died again to the enemy adc .
then i started roaming and helping other lanes , and the very same skarner called me a troll. i never fed or insulted anyone.
it's not the first time that people troll pick or troll games with the excuse that you should not take normal games seriously , and these are the ones who also ask others to play seriously their troll games. it's so annoying.
