What is when a guy says we have a lot in common?

When a guy says "we have a lot in common," it usually means that he has found similarities between himself and the woman he is speaking to. These similarities could be a shared interest in a particular hobby or activity, similar values and beliefs, a similar sense of humor, or a similar life experience.

By highlighting these commonalities, the guy is trying to establish a connection with the woman and demonstrate that they have potential for a strong relationship. He may also be trying to gauge her interest and see if she feels the same way.

However, it is important to note that just because someone says "we have a lot in common," it doesn't necessarily mean that they are actually compatible or that a relationship will work out. People are complex and relationships are about more than just shared interests. It's important for both parties to take the time to get to know each other on a deeper level and determine if there is a real connection beyond superficial similarities.
