One moron said that it is a word used to describe people who are against the Church of England. They spelt it wrong as well-it's *establish* not *astablish*.

Actually, antidisestablishmentarianism is the belief held by those who are against people who are against the unity of the Church of England and the Monarchy.
It is broken down like this:

*Anti*-Against, *Dis*-the removal of
*Establishment*-the Monarchy and Church
*Arian*-person or group,
*Ism*-a belief
