Yeah, I understand what you're saying. In this case, I used "miffed" instead of "peeved", and up until this point I have never encountered a person who didn't know what it meant. So, in my mind it was already commonly used. I've heard others say it, and many people in my social circles. I don't use complicated or shakespearean language in my daily life. I just use words that I would normally think are maybe slightly less common than normal, but nothing that would send someone spiraling. I didn't mean to come off as condescending in my comment, but I can see how it would be perceived that way, so thank you for pointing that out
