What's the deal with your nickname? How did you get it? If your nickname is self-explanatory, then tell everyone when you first started using the internet, and what was the first thing that made you say "wow, this isn't just a place for freaks after all?" Was it a website? Was it an email from a long-lost friend? Go on, spill it.
First initial, meet last name. The resulting appellation will start out simply as part of various email addresses, and then will inevitably become the breezy way to refer to its bearer by various coworkers. Other monikers will derive, in a similar vein as Cockney rhyming slang: "scody pop," "scody-scooby-do, where are you?" etc. This will replace previous, more irritating nicknames (e.g., "Olive Oyl," "the crazy
redhead dirty-blonde down the hall who's always babbling about
her close, personal friend Paul Weller"), so it will be a pleasant change of pace.
