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)

  • There is no such thing as words a foreigner shouldn't use, just to be blunt about it. – Lambie Jun 15 at 14:43
  • Even if it were clear what you were asking (a concrete example from your experience would help), a question asking for a list of phrases or words is simply too broad. – Andrew Leach Jun 15 at 14:49
  • 'Teenspeak' is the language of teenagers etc. Oldsters tend to like misappropriate some of this to try to appear cool, and end up looking not so hot. – Edwin Ashworth Jun 15 at 15:02
  • You should never use that casual form of address which has occasionally been called hailnames because the unavoidable sense of false intimacy by a foreigner inevitably comes off as both fake and insulting. It is completely out of place. – tchrist Jun 15 at 16:51

    @tchrist, even though I knew the question will likely be closed as too broad, thank you that you made it in time and gave some useful information. – Ramid Jun 15 at 17:12
