postmodernism
Postmodernism is a movement thought up by the French, and promulgated by academics which has contributed massively to all of our lives by:

1) ensuring that no child going to school in the 70s and 80s was taught grammar
2) confusing the hell out of, causing to fail, and generally annoying any uni student studying philosophy or law
3) of course the veracity of (1) and (2) depend on context, and truth is subjective, and as all meanings are a product of both THE MAN and THE SYSTEM what you say is only valid from your own point of view as is this whole urban dictionary entry, anyway

All the people who thought this up, and continue to promulgate it, and make people write essays about it, will be the first against the wall when the revolution comes.
The planes flying into the twin towers didn't cause them to burst into flames and collapse, using a different frame of reference, in accordance with postmodernism, the towers collapsed of their own accord in line with the inevitable consequences of capitalism
