What is your feeling about obscure cultural references that you either do or don't get?

I don’t know if this is an obscure reference or not, but I imagine that it is unlikely to be gotten by many people born after 1990. When I made it, I kind of tickled myself pink. It’s a kind of code, I guess—secret code that only members of a certain club will get, but I have no idea who the other members of the club are. Yet.

When I was young, and people made references I didn’t understand, it drove me crazy. Now it pleases me a lot to understand things I wouldn’t have understood back then. Of course, there are plenty of references my children understand that I don’t get. Just last night, my son was laughing and saying to his sister, “did you hear that? Dad doesn’t even know who mmph mmph is.” Sigh. What goes around, comes around. I think he was perfectly thrilled to know something I didn’t know.

What do you feel when you either do or don’t get something that someone else either does or doesn’t get? What is that feeling about? Do you have an example of this phenomenon?
