I try not to be a snob about terminology not everyone is an expert.
One time does stand out though.
Had a guy stop by the shop several years ago unannounced looking for set of
“F*^king perfect brain cards!”
According to him this was for his recent rare find of a Paragon that was one of a few left on the planet and thus incredibly valuable even though it was missing said “Brain cards”
He would have loved to offer it to me but he knew I would just take the “Brain cards” out of one of the many lesser games I had sitting around and “flip it for a mint “ 
We started keeping the doors locked after that. I don’t know if it was the terminology or total experience that has stuck with me so long.
