Well I suppose I should post mine here, I'd been putting it off:

I got online spring of '96. This was my senior year in high school. I had just returned from a year as an exchange student in Belgium, and had been accepted to MIT for the fall. So I chose

belge4mit.
belge (Fr. belgian), MIT (En. Massachusetts Institute of Technology). I honestly don't know why I chose 4 to join the two.

Anyways I kept the name when I arrived at MIT to make it easier for others to email me (that was the plan) but MIT restricts you to 8 chars so I lost the 2nd e. I use it now because it's more unique than 'bob'.
