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.
