Definition: "Isbull" refers to a bird, specifically an owl, which has white feathers on its belly but black (or iris) on top. This term can also be used in relation to something that glows or looks like it's glowing, often with an iris-like appearance. The word is from the Bible and was likely a reference to something resembling a bird of prey, possibly a falcon, which had white wings and iris-colored feathers.
