grilf
 //, n.

   Girlfriend. Like {newsfroup} and {filk}, a typo reincarnated as a new
   word. Seems to have originated sometime in 1990 on {Usenet}. [A friend
   tells me there was a Lloyd Biggle SF novel Watchers Of The Dark, in
   which alien species after species goes insane and begins to chant
   "Grilf! Grilf!". A human detective eventually determines that the word
   means "Liar!" I hope this has nothing to do with the popularity of the
   Usenet term. --ESR]
