Toxic and Salty Player

I just played a game of aram, all started off well with me playing i've been on a losing streak so i was eager to win one. After a little while in the game the enemy (-- removed summoner name --) started to call me a noob and bad at the game, indicating that i was unranked and that i had no skill. Throughout the rest of the game these taunts continued and i reacted accordingly until i decided i wanted to teach the player a lesson for being toxic so my team and i aced their team multiple times eventually pushing to and destroying the nexus to which fizz stated "gg annie did everything", i ended up with a score of 15/4 and was happy tp see the game over. I guess this example kinda shows why you shouldnt be toxic in any game mode
