First blood, you're not worth playing with

Our adc {Removed by Moderation} and me support were agaisnt and . We were getting hit pretty hard by garen's Q and yummi's slow, when garen hit lvl 2 he flashed into me with Q and E with yummi's Q and ignite. I died almost instantly and MF said something along the lines "This stupid support" after a brief moment i thought. "Well we can still win this. this is just a minor setback" but then MF said "I can't i quit i will not play anymore" and literally semi afk'd on the lane spewing curses on english and chinese also feeding the enemy team, I tried to help the others lanes but we couldn't do much with this person's quitting all hopes of victory. This was a normal game... (Re-posted since i couldn't remove previous screenshot that aparently should had been censor the name of the player)
