Greedhead (noun): An avaricious person; a thieving, blood-lusting, & cash-hoarding elitist who gets off on making life more difficult for more people, usually economically or politically.
Hunter Thompson used greedhead often in his writing.
From Hunter S Thompson, "Stadium living in new age":
But what is Daniel Snyder really up to? Is he as stupid as a chicken on a freeway? Is he a natural fool?
No. The Redskins owner has been called many things -- from a treacherous greedhead to a savage jackass -- but he is rarely called a fool. Snyder is a high-rolling businessman in Washington D.C., the crossroads of power and politics in a nation of dangerously frustrated warriors who love football and hunger for personal Security.
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.
