Another abbreviation for science fiction is "SF". However, "sci-fi" is more common in popular usage. Despite almost universal acceptance of the word, many older science fiction fans still cringe when they hear it.
Sometimes the word is used to mean particularly poor or campy examples of science fiction. For example, under such usage, Plan 9 from Outer Space might be considered sci-fi. In this usage it is often spelled "skiffy" which is pronounced to rhyme with "jiffy".
Another source of dislike for the sci-fi term is the tendency for the mainstream to use it as a collective term that lumps together not only true science fiction but fantasy, horror, comic books, cult films, special effects action films, and even marginally related genres such as anime and gaming.
