What annoys me is when internal code names are used all over the place throughout the code base. Sure it might make it easier for those steeped in years of company culture to navigate the code, and provide a slightly more playful company culture, but it makes it an absolute nightmare for a beginner to find things. Furthermore, I often see companies use trademarked words for internal code names, which could lead to problems if their usage is leaked outside the company. I can’t remember what it was but I recall reading that such use of trademarks for internal code names led to legal issues for a company.
