Read threads about soloing and just building characters, sometimes somebody will post something like; 'You did this and this solo, you must be a Munchkin.' Know about the Steve Jackson Munchkin card game where anything goes, but ... what is a Munchkin in reference to Co8 TOEE?.
Naw, but if you do nothing but always take the most powerful items and choices for the sole purpose of "winning" or "beating others" at a game that is not designed to be competitive in that way, even if it make no sense in gameplay (a Dwarf with a Falchion?! e.g.) then you are a Munchkin.
