Contraction of 'god did it', a sarcastic term to show that the
explanation for something is based on
religious belief, and not sound arguments.
Much used for arguments presented by IDiots and other religious bigots who are too lazy, or too stupid, or too dishonest to acknowledge that there are proper scientific
explanations for most things.
It is in particular used to explain 'irreducible complexity', a vague term used by IDiots to prove that god created the Universe.
