I voluntered to dress up on Halloween for a costume contest at work. A group of us are going to enter a costume contest as geeks through the decades. The head of our department is going to dress up as a 50s/60s geek. Someone else is dressing up as an 80s geek. We even have one guy dressing up as the Blue Screen of Death.

I, stupidly, volunteered to dress up as an Uber Geek. Two problems: First, I'm not sure what an Uber Geek is. Second, I need some ideas for a costume that will have others at the costume contest understand the point I am trying to get across. Our group will have a spokesperson who will explain what each of us are, but our group will be judged by a popular vote of those attending, so my costume must be basically understood.
Any suggestions would be appreciated.
