There are a couple of expressions that might provide some insight into the particular Jerryism I'm about to share.
The first expression, "Cock of the walk," is usually used to describe a man who acts as if he is more fashionable, important, brilliant, etc., than other people.
The second expression, "As nervous as a rooster in a hen house," has many variations. No explanation needed, I think.
