A speech code is defined as a historically enacted socially constructed system of terms, meanings, premises, an rules pertaining to communicative conduct. The theory, created by Gerry Philipsen, claims that wherever there is a distinctive culture, there is to be found a distinctive speech code. An example of this is present in groups of friends that hang around each other for long amounts of time. I have numerous sayings and inside jokes with my friends that no one who was outside of the circle would understand what we were talking about if they heard our conversation.
