Just Played the Worst Game of My Life

I thought these board could use more salt threads, so here is another. Little bit of context I am trying to gold so it doesn't look like a am a silver scrub, I'm pretty good (Trying to be modest) but my ranked games recently have been a bit disappointing to say the least. I just played the worst game of my life on league almost punched the wall next to me but i am not idiot and hurt my hand.

In the game first blood before minions even start, Azir dies. To lee mid, I don't understand but i got with it, Azirs early is good anyway. He dies again, and another time, this renekton say "noob". I tell him to stop flaming like the saint I am. I say if he says noob another time~~~~ i will slap my Johnston across his cheek. He continues to flame, i get fed because me and blitz are pretty good. Then the renekton continues to flame i say report him in all chat. He sits in base and refuses to help us as we start the team fighting phase. We then lose the game with me 22/4 there adc 2/7 and the renekton sat in base.

Sorry if I suck at posting i'm am jsut a silver pleb, I don't know why i have done this just some way to express my anger than headbutting the wall next to me. On the bright side got some nice KDA.
