What is when a guy calls you by his last name?

When a guy calls you by his last name, it can be a sign of familiarity and affection, indicating that he considers you to be part of his inner circle. This practice is often seen in military settings and sports teams, where members refer to each other by their last names as a sign of respect and camaraderie.

In some cases, a guy may call you by his last name as a way to flirt or show interest in you. This can be a playful and lighthearted way to interact with someone, and it may indicate that he feels comfortable around you.

However, it's important to note that this behavior can be viewed as objectifying or disrespectful in certain contexts. If you feel uncomfortable when a guy calls you by his last name, it's important to communicate your boundaries and ask him to refrain from doing so. Ultimately, the meaning behind this behavior will depend on the individual and the situation, so it's important to pay attention to the context and your own instincts.
