How did you get your username?

In 2007 I was a low ranking Soldier overseas in Iraq. We had lan lines going between three "buildings" to play 16 man Halo 2 multiplayer on Xbox. It was a great way to relieve stress after missions, and I was an awesome Halo 2 sniper. We'd talk sh*t to the other guys through headsets, and you could hear them laughing from the other buildings. We all had our own gamer name that would appear in the match (ex: Jim, DeadEye, or Candybars). One day after a mission we started playing, and "Default2" popped up above a player that was just running around. So I sniped him. Turned another direction, and there he was again! Over then next five minutes he kept on popping up in my crosshairs, and I'd headshot him (not because I'm that good, but cause he was that bad). After the match was over I asked through the headset, "Who was Default2?" "That was the XO," one of my buddies said. Our XO (Executive Officer) was a very socially awkward person who was playing Halo 2 for the first time. He was known for his extremely long ear hair. It was at LEAST four inches long when stretched out. No one, and I mean NO ONE would talk to him about it, even though he would play with it and stretch it out all the time! Through the headset, which resonated through the TVs in the three buildings, I said "I'm sorry about that, sir. I was just trying to snipe off your ear hair." All three buildings erupted in comments like "OOOOOOHHHH SNAP!! YOU JUST GOT SERVED!!!" "OH NO HE DIDN'T!" Everyone came over to congratulate me, and remind me how screwed I was. Long story short I was on sandbag duty for a few days, but his ear hair was gone the next day, and I got my name: [b]Ear Hair Sniper[/b]
