Halo!

So I've been playing Halo 3 for like... the past week straight and it's been bothering me. Winning match after match and no skill up. So my question to you, what is one of your most serious annoyance?

My Answer: Those dumb people who can't be good sports about losing. Last night me and my buddy were playing and this guy just wouldn't shut up about us beating him horribly. After the match all he did was talk trash and couldn't get it through his head that we're just better than him. It annoys me major time when people are complete idiots like that.
