You could just go off spur like me and place words that bare little relevance to much else, or anything for that matter, and piece it together to create something different and new that you'd think no-one else would ever use anywhere else.
Oh... and don't forget to leave off a letter and claim you did it on purpose and henceforth keep it that way.
But as Grindspine put it, choose a name to reflect yourself. Hell, even a common name would work, really. If you feel you like it, and it suits, go for it.
(and while I'm contradicting my own name, I did put thought to it, do have a reason for it, and the 'e' really is a spelling error that stuck because I felt it made it less likely to occur among those with any sense of spelling or grammer).
Good luck finding your inner chi... I mean, online name, Mai.
