It's possible that:
* It's a misspelling: Perhaps you meant a different word, like "fuchsia" or "facade"?
* It's a regional term: "Fadia" might be a term used in a specific community or region.
* It's a made-up word: The word could be a neologism or made-up word with a specific meaning for a particular group or purpose.
To get a clearer answer, please provide more context:
* Where did you encounter this word?
* What was the context surrounding it?
* What do you think it might mean?
