Jargon code is a secret language or phrases expressed in it, used to communicate secretly. It is often used by the military. “Tora! Tora! Tora!” is a famous jargon code used by Imperial Japanese Navy, denoting an order to “carry out the attack on Pearl Harbor.”
The use of jargon by outsiders is considered by insiders to be socially inappropriate, since it consitutes a claim to be a member of the insider group.
Jargon is used in sports, where technical sportsman terms but also sport-related metaphors for other events in life are used by sports fanatics for the aforementioned purposes.
The jargon of "jargoning" itself evolved from a pleasant wheew about the time of Samuel Taylor Coleridge, who referred in The Rime of the Ancient Mariner to the "sweet" jargoning of birds to today's usage, which is "unpleasant sounds I don't understand".
The origin of the term code monkey is likely the older term tape monkey, and is related to the jargon term one-banana problem.
Modern use of the term often applies to amateur computer programmers who stitch together snippets of code found on the internet and in books to make an application, without having an appreciation or understanding what the principles behind the code or the concept of coding are.
Code monkey also refers to subordinate programmers who are required to produce large amounts of code.
