Supercilious

Adjective - having an air of contemptuous superiority.

Origin: from the Latin superciliosus - 'haughty', from supercilium - 'eyebrow'

"Look at me, I'm far more supercilious than you'll ever be."
I really dislike this guy.

Supercilious, such a supercilious word. Sitting there, looking at me with one eyebrow raised and a contemptuous (great word) smile smeared on its lips. Does it have good reason to act this way? Maybe, it is good word to say and its origin and meaning do place it at a higher level than words like 'better' or 'smug'. Do I have to like its behaviour? Most certainly not, there is nothing more irritating than a good word which knows it's good and acts accordingly.
