I don't understand the point of someone trolling in a game, I am actually tilted.

My last game, I wasn't paying attention to champion select. Got into the game and I see that I have a Teemo support. I ask "Why do I have a Teemo support?". He replies, "you want support?" "Go fu* urself". I proceeded to not say anything because I realized this man is easily tilted. He then continued into lane and just stood in bot brush running back and forth not really doing much. Then the enemy bot hits level 6. All he proceeds to do is stand in front of Sona/Jinx and auto attack, disregarding both of their ults and CC. He does this 5 times, and every time I criticize him, he says "go" "fu*" "urself". I consider this game a loss, report him after the game and leave. I look at his match history out of curiosity, and his recent KDAs, CS, and other things suggest that he is not applicable for the Platinum level.

Then I see his emblem: Dynamic preference

Explains every single reason on why he is at the Platinum level.
