Yes it IS an idiom, because it's meaning cannot be understood by merely knowing the definition of the individual words.  It isn't a literal translation.  You are not literally sticking to something, as in adhering to it.  Idioms are also known as "sayings," by the way, to non-linguists.  :)

That depends on how you are using it.  You could use it to imply that you are talking about one of the earth's ecosystems.  Or, you could be talking about your immediate surroundings.  I would go so far as to describe social climate.  It could also mean current mental state.  That's all I can honestly think of.

I have never heard that word before.  If you get the answer, i would like to know it.  Maybe it's just the lack or sleep and coffee doing your friend's talking, and he thinks he's a dictionary.
