When I moved schools at 10/11 there was already another 'Tom' in my class so I was 'Tom-2'. I then used that and it became T2 when I started playing CS 1.6 as a teenager - then when I got an Xbox and Xbox Live, I tried to use the gamertag T2 and was told 'not available' as it had to be 3 characters or more!
So T2 + NA (not available) made the most sense. And here we are 22 years later as T2NA still!
