Such a dumb way to lose a game

last game i had a cho and lux that were in the enemy base and the only one trying to end it was lux, cho was just farming the minions in their base because he said he wanted them to feel "A Painful loss" or some shit like that. 20 minutes later they come back and we lose. i kept pinging him to end the game but his jackass refused to so i wasted like 50 minutes on a match that we lost which i should have won in 30 minutes. so sad
