Unctuous

I'm always looking up the definition of words in order to prevent looking like an absolute tool while stupidly misusing words I think I know.  Today I used my free dictionary app and looked up the word "unctuous" thinking it meant creamy or rich.  It did not mean either of those things.  The app stated it meant "having, revealing, or marked by a smug, ingratiating, and false earnestness or spirituality".  I stroked my chin thoughtfully, and then, all of the sudden an ad for Fox News popped up.  Now tell me that my dictionary app doesn't have a sense of comedic timing.
