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.
I tend to remember everything I read/watch/hear/do... Except useful things like where I put my keys or why I walked into the kitchen just now. As I result I appear to know everything but this is just a clever trick I use to fool people who have no existing opinion on a subject. Anyone who's actually studied a subject can disprove anything I say, no contest. Hence the name.
Pseudo: not actually but having the appearance of; pretended; false or spurious; sham.
