The term "flying monkey" comes from the fictional character of the Wicked Witch of the West in L. Frank Baum's *The Wonderful Wizard of Oz*.
The Wicked Witch uses flying monkeys as her minions, hence the term "flying monkey" is used metaphorically to describe:
* A person who carries out someone else's malicious intentions, often without realizing the harm they're causing.
* An individual who blindly follows or supports someone else, even if it means acting against their own values or better judgment.
So, while there's no single word for a "flying monkey" in the real world, the term itself is used metaphorically to describe a specific type of person or behavior.
