fan

n. Without qualification, indicates a fan of science fiction, especially one
who goes to cons and tends to hang out with other fans. Many hackers are
fans, so this term has been imported from fannish slang; however, unlike
much fannish slang it is recognized by most non-fannish hackers. Among SF
fans the plural is correctly fen , but this usage is not automatic to
hackers. Laura reads the stuff occasionally but isn't really a fan.
