Do guys talk about who they like?

So I noticed my crush was looking at me for a few minutes and a guy that he talks to sat next to him and was looking where he was looking and then looked back at him and then I noticed he said something to him and my crush started nodding and smiling and then they both were laughing and smiling and I don't know if they were talking about me or not as they were both looking.
