Do you know this feeling, when somebody is trying to use a word they heard somewhere and think that it's relevant and will be suitable, but it actually isn't because they are not the generation that should be using this word, or they are not natural enough, so you understand that they don't have experience in what they are saying. That they didn't go through some events or experiences crucial in order to use this word.
Don't get me wrong, I'm not talking about politics or the famous N-word. What I'm trying to describe is this feeling of discomfort a person might have when their parents try to use some neologisms in from of his or her classmates.
By asking this question I'm earnestly trying to prevent a situation when I'm using some quite rare word (0.00001% on Ngram), but it turns out that this word has quite a history and only a certain group is found acceptable to use this word.
Therefore, my question is:
In UK and US contexts do such words exists and if so, which ones exactly?
(We're talking about things of the 10 power -5 or -6 of Ngram)
