Talking to a stonewall

Holy fucking shit! I can't believe I'm this pissed off just because my friend has the memory of a gold fish. It was all over a game of Lol too, I know fucking stupid right. Starts the game out running into the tall grass nearly gets killed, walks into it 4 minutes later I run in and tank them as he runs away. I in turn get killed and he thanks me for dying. Says I walked in first and got myself killed, ok whatever man.

I then proceed to save him a couple more times, without dying. I get a little annoyed that he keeps blaming me for "running in" I then ask why he doesn't help me when I'm dying. "Well I know death is coming" yeah OK I just saved you about 4 times whatever. He retells what happened making it sound like I was not helping at all. He starts telling me to quit complaining which makes me more mad because I was just trying to understand what he was thinking, when he runs into a crowd. I tell him I was just trying to understand because I don't fully understand. He again tells me QQ stop complaining.

I just snapped, I was not going to let him shit on me, twisting my words to make me seem bitchy. I couldn't contain any of my rage to form any sort of a comeback, I started spamming chat and name calling. He does this on such a regular basis that I try to reason with him, sometimes multiple people will notice how stupid he is and he still thinks himself in the right.

In hindsight I acted childish at the end but I just couldn't stand the stupidity

It's like playing chest with a pigeon it knocks the pieces over, craps on the board and struts around victorious.

TL:DR Pissed over friend recalling game events wrong.
