Looking it up, I don't find any immediate references. Maybe it's a misspelling or a mix of words. "Seksi" in some languages like Indonesian or Malay means "sexy," but "Inis" and "Gjoni Tu" could be something else. "Gjoni" might be a surname, possibly of Albanian origin (since "Gjoni" is a common surname there), and "Tu" could be part of a name or a term from another language.
