Origin:
late 19th century (originally US): apparently an alteration of voodoo. It originally denoted a person who practised voodoo, hence a hidden cause of bad luck (hoodoo (sense 1 of the noun)). hoodoo (sense 2 of the noun) is apparently due to the resemblance of the rock column to a strange human form, often topped by an overhanging ‘hat’ of harder rock.
