The fact that you reference Lisp makes me think you already know the rule you're referring to:

https://en.wikipedia.org/wiki/Greenspun%27s_tenth_rule

> Any sufficiently complicated C or Fortran program contains an ad-hoc, informally-specified, bug-ridden, slow implementation of half of Common Lisp.

Related is Zawinski's rule of software:

https://en.wikipedia.org/wiki/Jamie_Zawinski#Principles

> Every program attempts to expand until it can read mail. Those programs which cannot so expand are replaced by ones which can.

Yes, I had both of those rules in mind, but that's not quite the effect I was stating. It would be a corollary to Greenspun's rule: that said buggy half-Lisp will then start to take over the rest of the program, usurping first the other configuration languages and then the core functionality. (Javascript in the web browser comes to mind as another example.)
