Well, I took a poll, and it seems that the majority of the Xbox Live community will make fun of your gamertag no matter what it is if it means you'll howl like a dying little girl into your microphone.
So pick whatever you like, because no one else will.

mine used to be metalsonic. some years ago i used to get made fun of for having a sonic the hedgehog GT. it wasnt alot but enough people would make fun of the name.
but i also made a ton of friends because of the gamertag as well. they were younger than me though lol. i kept the gamertag for years and then made a modification to the name but maybe a year later i finally changed it for good.
