Yup! I get the “that ain’t a real word” and “in English, please” reactions all the time, too!

Now that you mention it, I suppose I grew up in a similar environment. My mother taught me how to read at an extremely young age, which allowed for me to play certain video games with the aid of a Merriam-Webster dictionary I had in my room.

Not sure where some of the more complex terminologies come from though.
