In games, websites and forums such as this one, some people grab usernames from their favourite characters, while others come up with the most clever ones.
Post some of your favourite usernames that you've either seen or created, and if there is one, give the story behind it.
(If you're thinking I made this topic due to my lack of creativity and desperation for a good username that I can steal...Congratulations, you're right! Just kidding.)
I would say how my username was formulated, but that would be inappropriate.
