If a pattern is a common problem (e.g., becoming accustomed to a spectacular view) and generally-useful solution to that problem (blocking the view so that effort is required to obtain it), then an anti-pattern is what?

I think most people think an anti-pattern is an aberration in the "solution" section that creates more problems.

So here, the anti-pattern is that people use a term so casually (e.g., DevOps) that no one knows what it's referring to anymore.

(The problem: need a way to refer to concept(s) in a pithy way. The solution: make up or reuse an existing word/phrase to incorporate the concept(s) by reference so that it can can, unambiguously, be used as a replacement for the longer description. )
