You know when someone is talking about a band, book, movie that is allegedly hip the first tendency is to explain how you already knew about it. Such as, "Yeah, it's pretty good I have it in the rotation since the spring of 05." I was thinking that it would be fun to do the opposite from now on. For example, if someone introduces something to me that I already knew about I would act like I didn't know about it. I might actively try to assert my uncoolness. This is probably trying too hard, but I still like to think about how much find it might possibly be. In the same vein, it might be cool to try and introduce bands to people that you know have already moved past them.
