This is one I saw on another board I stopped by while trying to look for help on a laptop I'm going to be working on in a couple weeks. Basically, all you do is post one(1) thing you hate. It could be a current annoyance, or one you just generally despise. One per post, and we just go. It's not really a game, just to get it out there and see what other people are annoyed by. It helps to start them with "I hate" but you don't necessarily have too.
I hate the instant replays in today's sportscasts, especially since they don't bother to put up any graphics on the screen to say that it's a replay. It's not so bad when you're watching it from your house, but when you're out at the sports bar and they don't have the sound up for you to hear the announcers tell you it's a replay, then it's confusing as hell.
