unknownuser404 

A saying used to describe a user who is VERY unknown, more than an UnknownUser, so you add a 404 because 404 is a very mysterious number. People like these are very obscure, have no documentation on the internet, or are just non-existant.

Have you heard of Bartholomew Bach J. Fredericktown? Uhh no dude. He's such an UnknownUser404.
