RTS games. Whenever all the AI sit around for god-knows how long, then just randomly decide to launch an assault all at the same time; this leaves me fighting off an army roughly 7x the size of my own, and you don't have to be some sort of genius to realise that this is a very bad thing once even mid-tech units are available.
What's worse though is when they all take it in turns. The never-ending stream of enemies draining/interrupting my resources, hindering my research and slowly closing in on my most important structures makes me rage hard. It can eventually get to the point where I'm fending off big tanks with light vehicles, which is where I just draw the line and restart before I break something.
