I can't thik of any times that I've made someone else ragequit, though that may have more to do with the fact that I don't have a mic. Well, that, and because I don't normally play online all that often for anything other than Dark Souls.
...I'd be lying if I said I didn't ragequit from time to time myself, though. One of the funnier times I can think of is actually in Dark Souls. I had two humanity and after finally getting inside of the catacombs (intelligence builds don't mix with faith weapons) I found a bonfire. Wanting to get it kindled right away, I sat at it and revived to human...only to be immedietly invaded by uberpwnagemegastrong. The match didn't last ten seconds; the guy found me and one shotted me with his giant log-club. Precede that incident with a lot of bad luck involving the Smough and Orinstein fight, and you'll know why I quit there.
