Waterhead (noun): According to the outlaw-journalist Dr. Hunter S. Thompson, a waterhead is a weird (in the lowest sense of the word) individual, often of some social/political power that achieved said power through nepotism or by being a Greedhead.
It is implied that this weirdo has no brains & no real value other than to be Doomed. A waterhead behaves as a stooped, irrational blemish to his/her country.
From "Where the Buffalo Roam", based on the twisted legend of Hunter S Thompson:
The Gallow brothers -- Ernest and Julio -- party guys who had skinned a few Mexicans and forced them to carry them on their shoulders down to the pre-game tailgate parties at the colosseum. The Pepsi and Coka Cola bottlers of America -- Coke adds life; It's the real thing -- bombarded by missiles; flying flaming matchbook covers. The waterheads from General Motors up in the top seats where they belong; getting the worst of the pollution. All sorts of weird motherfuckers were at the game.
