This is not a standard Tagalog word but it refers to a werebeast (like the werewolf or lycanthrope of the West) in the Visayan province of Aklan.
Instead of turning into a wolf, a kiwig changes into a black dog or a wild boar at midnight.
Another Visayan monster:
Segben (in the Waray language)
– a hornless goat with large ears that clap like hands
– body odor is really bad
– appears only at night when its eyes glow in the dark
– waits for people to die the way vultures do
