mudhead

mudhead n.  Commonly used to refer to a {MUD} player who
   eats, sleeps, and breathes MUD.  Mudheads have been known to fail
   their degrees, drop out, etc., with the consolation, however, that
   they made wizard level.  When encountered in person, on a MUD, or
   in a chat system, all a mudhead will talk about is three topics:
   the tactic, character, or wizard that is supposedly always unfairly
   stopping him/her from becoming a wizard or beating a favorite MUD;
   why the specific game he/she has experience with is so much better
   than any other; and the MUD he or she is writing or going to write
   because his/her design ideas are so much better than in any
   existing MUD.  See also {wannabee}.

   To the anthropologically literate, this term may recall the
   Zuni/Hopi legend of the mudheads or `koyemshi', mythical
   half-formed children of an unnatural union.  Figures representing
   them act as clowns in Zuni sacred ceremonies.  Others may recall
   the `High School Madness' sequence from the Firesign Theater album
   "Don't Crush That Dwarf, Hand Me the Pliers", in which there
   is a character named "Mudhead".
