When someone saves their number as "exotic instincts" in your phone, it likely means they want to appear intriguing or mysterious. The term "exotic" suggests something unusual, alluring, or foreign, while "instincts" implies a natural or intuitive behavior.
By using such a unique and enigmatic name, the person might be trying to create a sense of curiosity and capture your attention. They could also be attempting to portray themselves as someone with unique qualities or interests. It might be their way of standing out or leaving an impression on you.
However, it's essential to remember that interpreting the meaning behind a saved contact name can vary widely based on individual personalities and intentions. The best way to understand the reason behind it is to communicate openly with the person and ask about the meaning or reasoning behind the chosen name.
Additionally, while it may seem playful or intriguing, always proceed with caution when building relationships or getting to know someone new. Take the time to understand their intentions and ensure that your interactions are based on mutual respect and genuine connection.
