Gamertag 

A gamertag is a person's online persona over xbox live.

You need to pick it wisely as Microsoft will try to get as much money from you as possible because it costs 10 dollars to change it.

Also there are unwritten rules when it comes to creating your gamertag.
Rule #1: It may contain at least 1 marijuana reference.
Rule #2: It may or may not (your choice) reference alcohol or boobs.
Rule #3: It must have 3 x's somewhere in the gamertag (perferably at the beginning and the end)
Rule #4: If you are 12 years old and are planning on playing halo 3 all day after school until your bedtime you must put MLG in the beginning of your gamertag.
Rule #5: You must, MUST make it look you're so retarded that you spent your whole time as a baby in a washing machine.

Here are some examples of gamertag you might want to use.

Gamertag 

I saw a guy with MY NAME as his gamertag the other day. All the more reason to believe that the YouTube filth is actively trying to downplay how effective this has been and in doing so demonstrate exactly how terrified they are of me getting in front of a camera with the full weight of both my accomplishment and what has been happening to me. That and ALL THE CRYING. They're giving themselves away. They know they're on borrowed time and THEY KNOW that they WILL NOT BE ABLE TO EXPLAIN AWAY A SINGLE DEATH. They won't be able to explain away their complicity in a flagrant violation of rights.

Hym "And that's why they need to create a narrative around what's happening. When what is happening is put plainly there is nothing other than petty breeders and the already successful robbing someone below the poverty line and preventing them from attaining recourse for a violation of rights done in the name of protecting women's right to molest a retard at work and coercing people into accepting the devaluation of their own lives for the sake of parents who wouldn't do anything to stop SOMEONE ELSE'S kids from dying... But (none the less) expect you be perpetually beholden to fuck trophies you didn't sire. If you strip them of their Hero vs Villain narrative what you're left with are greedy, selfish breeders desperately clinging to moral superiority they don't actually have. Seeing that Gamertag reminds me that the people acting against me have a vested interest LYING BLATANTLY and hiding the truth to save their own hides."
