I came up with this phrase a few years ago and wrote a blog post about it, and have incorporated it into a number of my conference presentations and training courses on Pluralsight and DevIQ.

Let's step back for a moment and talk about coupling, and then return to why tight coupling and the new keyword can be problematic.
