Scheisskopf: (German) (s.) (v.) shithead. Composed of the German words scheiss (shit) and kopf (head) and with the exact same meaning as the English equivalent. A person, of disfavorable disposition (i.e. jerk, asshole, scumbag, Cock mcNugget, fuckface, etc.)

There was also a character in the Joseph Heller novel, Catch-22, with the surname Scheisskopf. As I recall, he had a very bad temper and wasn't the brightest star in the sky. He starts out as a lieutenant and, throughout the course of the book, works his way up to lieutenant general and can be seen as a symbol of the disfavor among enlisted men, especially high-ranking ones, for officers, as he embodies pretty much everything an enlisted man hates in an officer.
