Anyone have stories of you simply "clicking" with another player?

What I mean is that the 2 of you are complete strangers, and had never met each other until that game. And yet, the 2 of you go off as if you had been playing together for years. I assume this happens most of the time in the bot lane, but it doesn't have to be.

For example: I played a game as Naut support recently where I did die quite a bit. Some of them were due to blantant mistakes in lane like trying to engage when I have an early game Vayne behind me. Not her fault that she couldn't follow up properly, it's just how Vayne works.

The rest of my deaths came from buddying up with my Yasuo to a point where I wouldn't be surprised if our teammates thought we were a duo. We weren't. In fact, we hardly said a single word to each other that game. He was roaming around on his own quite a bit, and me being support would roam with him. And so, due to the synergy between Naut and Yas, every time I died, Yas ended up getting a double or triple.....and we all know what happens when a Yas gets fed.

So, what are your guys' stories?
