IPA: /ˈbʊɡɪmən/
KK: /ˈbuːɡɪmæn/
A mythical creature often used to frighten children, typically described as a monster or ghost that hides in dark places.
Children often believe that the boogyman will come if they misbehave at night.
The word 'boogyman' originates from the Middle English 'bugge' (meaning a frightening creature or goblin) and 'man' (meaning a person). The term refers to a frightening figure or creature that is used to scare children.
Think of a 'frightening creature' ('bugge') that is a 'person' ('man') — that's why a boogyman is a scary figure used to frighten.
