Why does everybody want to pronounce this word as "Shitehead"? That's an entirely different word, from a Scots origin. Shithead is a very simple insult - it just means cretin, imbecile, unpleasant person, tosser, worthless pile of wank... just anyone who upset you recently. (and how do you change the pronunciation entry for an item that already has one posted???)
George Bush junior- what a fucking SHITHEAD!!!
