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

When a guy calls you by your last name, it could mean multiple things depending on the context and the tone of their voice. Here are some possible explanations:

• He might use your last name as a nickname or term of endearment if he is close to you or feels comfortable with you. This could signify camaraderie or even flirtation depending on the situation.
• He could also use your last name in a professional or formal setting to show respect or establish hierarchy. For instance, a teacher might call a student by their last name to maintain a certain level of decorum in the classroom.
• However, if the guy uses your last name in a demeaning or derogatory way, it could be a sign of disrespect or even bullying. In this case, it's important to speak up and let him know that his behavior is unacceptable.
• Finally, it's worth noting that cultural or regional norms may influence how people address others by their last name. For example, in some countries, it's common to use the last name first followed by the first name as a sign of respect.
