1) Reloading after every kill
2) Shooting doors that haven't opened yet (in Metroid Prime and any other game that has a similar thing to it)
3) Punching walls when waiting for elevators, load screens, first person story scenes to end, etc.
4) Not using a mic responsibly in any team oriented game. TF2, L4D, Borderlands, Gears of War, etc.
5) Halo/CoD hate. If you don't like the games, that's fine, but don't put those down that do.
6) Console gamers are RETARDS! HARDY HAR HAR! I have choice words for any ************ that thinks console gaming is stupid. I also have choice words for any ************ that thinks a mental problem like retardation equals a lazy problem like stupidity.
7) PC gaming is just too expensive. I like my consoles. I already have a good laptop. But $300 for a console + ~$600 for a good PC = $900. Add in some other peripherals and stuff you have to buy for the console, and you could have the money for a gaming PC - and no need for an extra one. I bought a laptop before I had even thought about this, so I'm not going to buy a gaming PC. But this is just food for thought.
8) Jumping through boss doors in Megaman X, Zero, ZX - Alright, this one might just be me, but it is a cardinal sin to not jump at the boss doors. You just have to, just to see your character float as the screen slides to reveal the boss backgrounds.
9) Pushing every button/tapping the controller/etc. during load screens.
10) Saving after every single encounter. I do this. Whenever I get past the tiniest challenge in a game, particularly shooters, I go pause and save the game on any game that allows it. When using emulators, I do the same thing with save states, which isn't cheating because you've already proven you can pass the obstacle in question. It is cheating when you use it as a way to get infinite lives. (Die? Reload last save state).
