Got mine by simply acting like an obnoxious Brit. My voice sounds funny(Probably thanks to my Di-George Syndrome that I have) whenever I use a mic, and it irritates people to no end on XBL. It was hilarious. Soon as I started trying to help my team I got hatemail telling me that I sounded like a 12yr old on XBL when I'm 18 lol. Ah turns out having Di-George syndrome can be funny on the internet.
I was host in a hardcore Kill Confirmed match. Some idiot killed me for some reason, so I returned the favor. Then I killed him one more time. His two buddies decided to kill me a couple times. Then I accidentally killed one of them and found out I was host. I didn't kill another enemy the rest of the game.
