It's possible you're thinking of a similar word:
* "Fito" could be a misspelling of "Fito", a Spanish slang word for "guy" or "dude."
* "Fito" could also be a shortened version of "fitó", the past participle of the verb "fitar" in Portuguese, which means "to stare at."
If you could provide more context, I might be able to give you a more accurate translation.
