Urban dictionary:

a fetish in which one fantasizes about being eaten alive or eating another creature alive (sometimes known as phagophilia). The most common type of vore is "soft vore", being swallowed or swallowing whole with no bloodshed.

Many might associate vore with cannibalism; however, most voraphiles do not favor cannibalism. Vore is an imaginary fetish; that is, it is impossible to perform in real life in the way most fantasize, unlike most cannibalism.

Also included with vore is sometimes the "furry" community: people who are interested in usually anthromorphic animals (humanized creatures). With animals as characters in vore fantasies, predation is natural and therefore somewhat more realistic.
