Kind of a dumb idea for a topic but whatever. Post your service tags and meanings here. Mine is XJ9 which if you don’t know what that is you missed out on one of the best Nicktoons.
Mine is RIOT, means im gonna raise hell in a match. Which i tend to do alot. Don’t ask how or why.
B312, Noble Sixes Spartan-III tag, he was in Beta company until he was pulled out after training, and his number is 312. But when Halo 4 comes, it’ll be S117, for Master Chief.
FRAG, for the obvious reasons. Also because I’ve been a variation of Frag Bait since Gamespy and Roger Wilco, so I answer to it without thought. Makes it easy for teammates to call out to me, since I usually play with a mic. And it’s one syllable, so “Frag, behind you” is easier for people to get out than “Double you three seventy seven, behind you!”
D34D, because I usually am.
6X9, because 6 x 9 = 42.
My current one is kind of personal, so I won’t post why I have it. The service tag I had before was “MATT”, “ODST” and “WOLF”.
Matt’s my name, I like ODST’s, wolves are awesome.
X02 (From the game Ace Combat 04: Shattered Skies, my favorite fighter jet)
Bito - same as my gt and its a nickname I’ve had for about 10 years.
Uny - Unykorn

You and I, both. I have the game, but I lack the system required to play it. D:
It’s my favorite out of the series, but I do own most of the others. That includes the Xbox 360 one called, “Ace Combat 6: Fires of Liberation”. ^^

Mine is 1983 - The Year I was born.
ROSE - reference to my favorite musician, Ryan Adams.
Mine is CELT, as i support Celtic FC football (soccer) club, and i’m an avid CELT :))
Mine is almost always 1337. Thats “Leet” or “l33t”. It’s my favorite number. And its the language of the internet 
Sometimes I put make it “01” for the 01 in my GT. K0lucc1
BTW, the 1 is an I. People have a tendancy to say “Kolucc”. Its Leet Speak!
And very rarely, in fact, so rare I have’nt even done it yet, S259. Just cause I like that number.
I either have S297 because it looked Spartanny haha - most of Noble have S-2xx, so I put 97 as it’s my birth year, or MOSH, for obvious reasons.
At the moment it’s EDDY because my name’s well, Eddie. But I can’t fit 5 characters.
Mine is D12, the rap group from Detroit. Also known as Eminem’s Buddies, but that wouldn’t fit.
FSU, because I fsu.
