The belief or doctrine that it is Americans' inherent right to consume massive quantities of food, expanding their waistlines from coast to coast.
If anyone questions why so many Americans are ginormously fat, simply refer them to the doctrine of Manifest Density.

A half-baked thoery that the USA could do as the fuck it liked. In practise, it got land and the begginings of an empire by paying for it before it started a revolution against the European powers that owned it. When the USA did try and annex Canada, a small number of the British army and a few thousand Canadians beat off the United States, leaving ti with the option of the treaty of Ghent, which didn't give them any land concessions (as opposed to the British-Canadian forces, which never intended to make any, so handed back all taken land without grudge) nor did it make either side any richer. As a courtesy, the Royal navy ended impressing.


When the united states wanted to start an empire, it went after a weakened spanish empire, which was on the brink of freeing itself. When the USA again attempted imperialism in south america, it was having a little trouble with fallen power Spain, so decided to pay $20,000,000 to buy a few POS nations that would have revolted in a few years anyway. Wow, isn't that clever? Obviously, these places have since gained independance. Quite possibly the worst empire ever...
Manifest destiny was retarded. Why didn't the US try conquering outer space instead?

A belief more ridiculous than Christianity

Or in normal people words, the belief that an arrogant piece of shit colonist can take over the land of native Americans because the piece of shit colonist is fucking arrogant.
Colonist: give me your land
Native dude: nah fuck you

Colonist: HOW DARE YOU! I have manifest destiny on my side!
Native dude: I wonder how you’ll react when hitler does a similar thing but instead of keeping the equal part of us he kills them.
Colonist: who the fuck are you talking about
