No, you want a singular definition and application. Rule of cool is a philosophy that can be applied in different ways. Its a game mastering tool that can both add a rule where none exists within the framework, or allow the rules to be broken in a particular instance. Its up to the wielder to decide.The issue with this discussion is that what you describe as rule of cool is what I would call improvised actions that still follow the rules. So what do you call people who follow the rule of cool like the OP's high jump example where it makes no sense? Because I've played in game where the DM says they're like the rule of cool and it's really "If you can describe something cool you can get away with Loony Tunes."
Without an agreed upon definition and at least loosely defined limitations, the phrase rule of cool is meaningless.
Enough with this, "I have to totally agree in all aspects or its meaningless for everyone" rhetoric please.
