WHAT THE FREAKING HECK JUST HAPPENED?

I just played a freakin game of which arguably we were winning. HOWEVER, some troll who was 6-1-0, we will call him Jax starts TPin in deep into the enemy jungle, throwing essentially, I would have to see replays of team fights after he started to throw.

Anyways after we lose 3 or 4 people and a drag, this troll throws up a surrender, three other people immediately vote yes practically before the vote was even shown on my screen. He freaking mind freaked those other three moroons...AND I LOSE FREAKIN 17LP?!

22 mins in, we were up in kills, down slightly in objectives but I'm 80% sure we weren't even down any inner turrets. We literally lost the first big fight of the game and the surrender gets thru man LP is hard to come by especially with a series for promos if I had won........

DAMN....

ever happen to you guys?
