Vaguelity is a form of a many-valued time reference (e.g. soon, later, sometime, etc...) or probabilistic interpretations of treaties and contracts (e.g. loophole); it deals with reasoning that is approximate rather than fixed and exact.
Time Referenced
Child Riding in Car: When are we going to get there?
Parent Driving Car: Soon
Probabilistic Interpretation
The loophole he is trying to use is the vaguelity of the UN treaty claiming that only nations and govenments can't stake claim to the moon.
n. software that is no longer sold or supported by the original publisher / developer, often found as free downloads on the internet because it cannot be obtained elsewhere. Not legal, but often seen as morally acceptable because the company that made it is no longer selling the title, nor releasing it as freeware, therefore abandonware is "keeping the gamealive", so to speak.
Doom II is not abandonware because idstill sells it, while The Incredible Machine is not sold, therefore is abandonware.
