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.
