Acronym standing for Getting Away From It All, used in science fiction fandom and coined in 1940 by Dick Wilson. When it was first coined, it meant a fan who was getting away from mundane persuits to engage in fan activities, but in a very short period it flip-flopped in meaning and was thereafter used to mean leaving fan activities behind to pursue real-world endeavors. See also: "gafiate".
I was gafia while attending college.
