A bogeyman (also spelled bogieman, boogeyman, or boogie man, and pronounced /bʊɡimæn/ or /boʊɡimæn/; is a monster that has no set appearance in the mind of an adult or child, but is simply a non-specific embodiment of terror. Parents may tell their children that if they misbehave, the boogie man will get them. In some cases, the bogeyman is a nickname for the Devil.
