a question for all native speakers of English

Sure.

When I read the Wall Street Journal, I better do so with a dictionary nearby, because there are often words I don't know.

When I hear songs, there is all sorts of slang I don't know at all - and that's assuming I can even figure out what the words are!

Even at work, different industries have their own jargon and it takes a while to learn it all.

Have you ever come across words or vocabulary or slang or phrasal verbs in your everyday conversation or in the newspapers or movies or songs that you don't know or understand their meanings that you have to guess? Are there a lot of them you don't know?

As for newspapers, I sometimes come acoss technical terms that are unfamiliar to me.
