My first gamertag was created when i was like 7 when xbox first came out & my default name was TouchierPlayer27 I got made fun of every game I joined for 2 years straight.. I had to get a name change.
My first gamertag I created was xDr x Klutchx69. I was only around the age of 10 and I didn't even know what 69 meant. But xbox gave me that suggestion because Dr x Klutch was taken. Lol!
My first gamertag was Fathom C Man, I was so young back then I didn't even know what it sounded like lol. I pretty much had to change my name a few months after I first made it.
