Final is a keyword in many programming languages used to define a variable, method, or class that cannot be changed or overridden once it has been initialized. It's like getting a tattoo on your face - once it's there, you're stuck with it forever (or at least until you get a new face from Neuralink).

How to use it in a sentence

• "I'm going to make this variable final so that no junior developer can screw it up later and bring down our whole system like they did at Twitter."

• "I wanted to override this method, but the original developer made it final. Guess I'll have to fork the whole damn library and maintain it myself, like everything else in this legacy codebase from hell."
