The Story of SPIDER
I don't like spiders. I did once have a pet spider named Brian. That, however, is not the origin of the name. The origin lies, again, in a slightly neurotic friend. One day in eighth grade, out of absolutely nowhere, my best friend informed me that I smile like a spider. Spider I have been ever since. An interesting note- one of the many ways of saying "you're crazy" in German is "du spinnst." The verb (conjugated in this form as spinnst) comes from the word for spider (or spinner).
How the Two Combined
This one's basic. I needed a screen name. All my many nicknames were taken. I chose the most important two and stuck them together, knowing there was no way whatspider was taken.
