If there's anything worse than getting completely stomped...

it's false hope. This will happen so many times, one lane gets totally smacked by the enemy team, such as the adc gets fed, and she becomes and unstoppable monster. Of course, with all the flaming going on, and the score being 5/20, you'll want to ff asap. You start the surrender vote at 20, since there's always that one guy who says no at 15. It's got 3 yeses, almost there! But right before someone enters in the 4th surrender vote, the other team, who was bming under nexus turret, made a lack of judgment and 4/5 of their team died. In result, the other 2 players vote "no", resulting in your game lasting less than 5 minutes longer than if you had surrendered at 20.
