I'm making pop culture references around people I know won't get them to make myself feel culturally superior
Why is it so important for you to appear culturally superior?
I want to feel culturally superior because I always want to be on top of everything
If you know that much about the topic, then there's nothing wrong with wanting to share it!  However, you shouldn't be doing that just to make others feel stupid.  Do it to feel better about yourself instead!
You should shut up.
I understand that you want to feel smart, and there's nothing wrong with showing off your mental capabilities. However you could really annoy people if you go around putting them down because you know more pop culture than they do and then you'll have no friends to share these things with.
