I just pure and simple hate campers.
You buy games to have fun, and I don't see how sitting in a hole, waiting for someone, and shooting them in the back is in anyway fun. Why pay £40 for a game to just sit in a hole.
Also people who don't play the game.
E.g. when it's your sides turn to be the attacking team (planting the bomb) and they just sit in spawn =/. You're meant to go and plant not camp =/. Just let the time run down and they then lose.
So annoying.
Oh and poor reg on CS:S
When you can actually see the blood splats that you have put on the opponents head, but apparently you didn't hit them?
Makes me FUUUUU so much.
