This is true but also the way her date phrased the response was pretty rude af. If someone references a movie I don't know, I don't go "La-dee-da, look at Mr. Film Buff over here," since that would be fucking rude (and I also like films, but that doesn't mean I know most of them).

I would probably instead say, "Is that a movie you like? Should I watch it?"

Sure, and it's fine when a meme flops. But this person was apparently being an asshole about the entire concept of memes.

My wife is into things I'm not into. Sometimes she even drops references to those things into conversations that I don't get. You know what I don't do? I don't say, "So, I'm supposed to memorize all these TV shows in order to have a conversation with you?" That's being a jerk, and completely unnecessary. I just kinda politely smile and nod, and move on.

I agree, you shouldn't expect people to understand every reference you make. My statement was more about how the quote in the pic and, to a much lesser extent, the comment above both seem to view being introduced to a new thing by someone you like as sort of a bad thing. The quote in the photo especially is a red flag of not caring about the things the people you care about are into.

Obviously not everybody is going to be familiar with the same media as you. But if somebody gets upset with you because you quoted a joke from a source that they're unfamiliar with, that's on them, not you.
