The most recent example in my mind would be during Final Fantasy 13, while playing as Lightning and Hope, up against the Aster Protoflorian, or as I like the call it "the mother fucker that looks like a giant bulbasaur".
It stomped me the first battle, tried a again, did better, died, tried again, did a little better, died, "Fuck this!", ragequit.
Tried a couple hours later, did a little better than before, died, tried again, did a little better, died, 'Fuck this!", ragequit.
DELICIOUS COPYPASTA YOU MUST TASTE IT
Tried a couple hours later, did a little better than before, died, tried again, did a little better, died, "Fuck this!", ragequit.
I beat him my next try a couple hours later, but there was a lot of "Fuck this!" that day.
