I used to be Strider from the LotR books, but when the films came out it became common af (PC gaming, where there were no unique username registrations). I was Strudel for a bit, as nicknamed by other gamers as an alternative.
I then got a console in 2009 whilst living with a flatmate and we created an account that was a portmanteau of our names to share; I'm Russ and I can't actually remember what the original name ended in.
When I inherited the console and it stuck in other places, I randomly switched to Russinating (as in 'resonating') as I wanted to keep my actual name in it but needed something totally unique for PSN, forums etc.
So yeah... long winded.
