[2020] What's the most ridiculous reason your team surrendered?

I'm genuinely curious what everyone's experience with surrending is.

Here's my own recent experience:

So I'm bronze III, hardstuck (ik, flame me all you want). Last game I played, I was playing as support Leona for a Jhin. The lane was going pretty well, Jhin ahead in CS by 20 (this is pretty normal in Bronze), and I manage to keep him topped up in health by zoning the enemy away. Then, for a moment, our "ward" or "scuttle" in the river expires and I go to put a replacement (because we were pretty pushed up and enemy jungler on botside too). All of a sudden, my ADC spam pings me to back off as soon as I leave lane to ward. He types, "shouldn't have left me in lane alone." Then right away, he starts an FF vote at literally 15. Obviously, 4 people say no as we were ahead. Then he ups and just quits the game altogether. Somehow, our Vladamir manages to carry us in a literally very close game, but it was ridiculous.
