No flips for you!
You keep saying I'm redefining a word, here, when I'm using it exactly as it's defined in the dictionary cited in this thread (you liked that post, even).Then we have no common framework in THIS universe because what you just said is complete nonsense.
You can't redefine words to mean whatever you want them to mean.
One of two things is going on, here. Either you're smuggling in some other concepts into the definition of negotiate, like maybe picturing a stiff, formal process where everyone's clearly aware of both the goals and the process, or you're just actively hostile to the idea that you're negotiating with players during play because it stands athwart your assertion that you're the boss as GM. The former is something I cannot do anything about except encourage you to not do this, and for the latter I'd encourage a bit more awareness of the study of social dynamics -- even dictators negotiate all the time.
