Drunk Monkey Spec (document) -- A spec or document that is so badly
thought out and written that the only reason anyone could think of
why it exists is that a Drunk Monkey(s) must have written it.

Drunk Monkey specs (documents) are most commonly found in military
and/or government documentation (but can be found in Dev and IT
documentation also), where they try to explain a complicated concept
to a laymen and utterly fail at; creating an ill-written, convoluted
spec (document) that even people in the field who know about the
topic can't make heads or tails of it.
