You know,
making it a point to use new vocabulary is the best way
to get it firmly into your
active vocabulary. I remember one time trying to use a new German word I'd recently looked up. My German friends looked at me as if I had three heads and asked me where on earth I'd heard that word. (As I recall, they were also doing a lot of eye-rolling when they asked...lol) At any rate, I told them I'd found it in the dictionary. I was promptly informed that nobody ever used the word and that I should forget it ASAP, because I would only sound weird if I used it.
Please explain to me the emboldened parts.

I know the meaning of each and every single word that I marked here but I cannot understand them as a whole expression.
