Grass
I noticed they used the word 'grass' a lot to describe an informer/snitch in this series. I had to look it up at first since I had never heard the word used in that context before. This is part of the Wikipedia article (https://en.wikipedia.org/wiki/Supergrass_%28informer%29):
The first known use of "grass" in that context is Arthur Gardner's crime novel Tinker's Kitchen, published in 1932, in which a "grass" is defined as "an informer".[2]
As you can see there it says that the term's first known use in that context was in 1932.
Anyone know if that article is reliable, or did the writers of the show really use a term 150 years before it was actually used?
