It's possible you're thinking of a nickname, a fictional character, or a person from a very specific community. Could you please provide more context?
For example:
* Is it a nickname for someone? If so, who are you referring to?
* Is it a fictional character? From what book, movie, or video game?
* Is it someone from a specific group or community? If so, what is the name of the group?
With more information, I might be able to help you find the information you're looking for.
