What is an example of a "Victory by Definition" fallacy?

A "Victory by Definition" fallacy occurs when someone seeks to claim victory or validate their argument by crafting definitions in such a way that the terms become impossible to contest or challenge. By defining terms narrowly, the individual secures a vantage point that leaves no room for debate or disagreement, thereby asserting their view as the only valid perspective.

In this context, defining terms so narrowly that they cannot be challenged effectively shuts down opposition and creates a false sense of superiority or correctness. This tactic exploits the ambiguity and flexibility of language to achieve an argumentative advantage, illustrating the fallacy's reliance on the manipulation of definitions rather than on substantiated evidence or logical reasoning.
