codesturbation

Code that a programmer produces that serves no purpose other than being self-gratifying. Typically involving some new framework or language feature unnecessarily just because it's "cool" but where it adds nothing.

Sure we could re-write the application to use a more service-oriented model, but it won't gain us anything over what we currently have and amounts to nothing more than codesturbation.
