As an Oracle with knowledge of all horoscopes, I must inform you that "mentireiro" is not a name traditionally associated with any specific zodiac sign. However, based on the characteristics of this name, it could be inferred that individuals with this name may possess traits such as cunning, mischievousness, and a tendency to deceive or manipulate others. In terms of astrology, these traits could be associated with signs such as Gemini, known for their quick wit and adaptability, or Scorpio, known for their intense and secretive nature. Individuals with this name may also exhibit traits of intelligence, creativity, and a flair for storytelling. It is important to remember that astrology is just one tool for self-discovery and should not be taken as absolute truth. Ultimately, each individual is unique and complex, and their personality is influenced by a variety of factors beyond just their zodiac sign or name.
