A malicious goblin, one name for the Devil, which was once in common use for frightening children. E.M.Wright in Rustic Speech and Folk-Lore gives as an example: 'If tha doesna leave off shrikin', I'll fetch a black bogy to thee', and cites a ghostly bogy which haunted its murderer as a skeleton, wailing: 'Oi waant my booans! I waant my booans!' It was universal over England, but the use of cautionary demons and nursery bogies has gone out of fashion in modern education. Now 'bogy' serves as a generic name for bogies in general, including a number of frightening and mischievous characters: barguest, boggart, brag, buggan, buggane, hedley kow, mumpoker, padfoot, tanterabogus, trash, and so on. The respectable and mediocre Colonel Bogey, whose golf score is always dead average, seems to have no right to his name.
