I had a QA Manager use "Pest Control" (bug squasher), which of course promted a QA Engineer to choose "Pest" :) I have also seen "Digital Entomologist", "Tall Blond Guy", "Bug Sniper", "Natural Born Coder", and a host of others.

Personally I have always been "NetMage", except the one time I was allowed to use Klingon Fonts, then I was still "NetMage" but in a totally cool, unintelligible font :)

"Nothing is sure but death and taxes" I say combine the two and its death to all taxes!
