Something or someone that is false, lame, or foolish. Pronounced shuh-rahd, as the British do. Believed to have been popularized by the Pink Floyd song Pigs (Three Different Ones), and a South Park episode homaging to that song. It can be used as an exclamation as well as a noun.
"Yo, I just bombed that math test!"
"Ha ha, Charade you are!"
"Yo I just banged your girlfriend!"
Empty or deceptive act.
I felt her apology was merely a charade and I did not accept it.
