So earlier this evening, I was playing some invasion. We enter the voting lobby and there are a couple of choices available, Invasion on Boneyard and Invasion Slayer on Boneyard. One person out of the 12 starts saying "Go for invasion, Invasion slayer sucks." Now, in my time playing Halo: Reach as well as the Beta, I became fairly familiar with how invasion and invasion slayer worked. So I politely asked "Hey, do you know how to play it?" and without even letting me finish starts talking loudly into the microphone. "Who the fuck was that? TimesHero? Was that you?" to which I replied "Yeah, there are alot of people who don't know how to play invasion slayer so I was-" "Oh yeah you shit talking pansy ass little bitch? You going to shit talk me? That's it, you're getting reported! Oh? What's this? File complain't? 'A' button. " so I said, "Buddy, what's you're problem?" and then the game started. Luckily he was on the other team. To make a long story short, my team ended up winning. In the post game lobby, I took the opportunity before everyone left to say "I win." and then I backed out of there.
Honestly, I've encountered my fair share of internet douche bags in my day, but nothing like that. Do you have any stories like this? I'd like to hear them!
EDIT: The game in question. I totally forget who it was. Now I didn't do so hot this round because I decided to be more of a distraction.
