This incorrect use of the word vore is now commonplace. īeing a fantasy, any orifice may be thought of as capable of vore, but it's really just adding a body part to the word vore. Most vorarephiles describe themselves as being ' prey' - based on how animals are considered to be prey for other animals who are in a higher chain position - while those who actually do the eating in the fantasies, are referred to as a 'pred' (derived from the word predator). The term vorarephile describes someone who enjoys vore.
The word is derived from the Latin vorare (to 'swallow' or 'devour') and the Ancient Greek φιλία ( philia, 'love').
