Code Mumble 

In order to maintain attention and focus during problem solving, a person may mumble random details related to the task. This can also help to drown out external noise and distraction.

Commonly occurs when software developers are deep in code but surrounded by noise and chatter.

A programmer talks to himself in code mumble, repeating logical steps to solve a problem while semi-engaged in office conversation.
