'Mundane' was originally used in the realm of roleplay, online or otherwise, to denote the person 'behind' the person online, like the puppeteer. In online text-based rp, its shortened to the word "mun."(1) And has since been made into a suffix conjoined by a hyphen to the screen name/handle in qustion (2) In gneral,its used to formally adress someone whose name you dont know, without having to do the totally n00bish thing of calling someone by their screen name, since their name is obviously not "StarWarsFreak." or "FluffyPuppy498746."

Outside the world of roleplay, a person's mundane is often used in lifestyle societies such as therianthropes and furries and vampires to indicate their sort of "alter-ego" when not assuming their persona.
