The word is supercilious, I think

I went to watch Little Miss Sunshine the other day (hilarious, by the way) and saw a trailer for this, a movie based on Idi Amin and his rule in Uganda. I'd always heard snippets here and there about this guy without knowing anything in great detail, so I came home and googled him. Turns out, he gave himself quite the title: His Excellency President for Life Field Marshal Al Hadji Dr. Idi Amin, VC, DSO, MC, King of Scotland, Lord of All the Beasts of the Earth and Fishes of the Sea and Conqueror of the British Empire in Africa in General and Uganda in Particular.
