Maybe the op's friend is a newbie and doesn't understand dive-ese talk. When a guy says you have a great set-up, he's referring to your gear, not your personal attributes. When he asks you if you'd like to see his sausage, he's referring to his SMB (surface marker buoy). When he says he loves going down, he's referring to the dive. If he tells you he has an incredible SAC, he's referring to his air consumption rate. I could go on, but I think you get the picture.
So many things can be misconstrued if you don't know the language.
