Sure.

In my head it looked like this:

   "I don't think this is an idiom" (meaning that either it is not an idiom or I am unfamiliar)
   "I am an authority on English, and it is an idiom"
   "Nah."
   "Here are the dictionaries" 
   "It is not in the dictionaries" 
   "Google it"
   "That's lazy, but sure. It is not on the internet"
   "Here, it is in a pdf used in education"
   "Fine"

I don't think that I am the arrogant or entitled one here. Also I don't understand why are you coming after me after this concluded. This, and your other comment. I very much don't like it.
