Farce (7)
I believe the answer is:
'farce' is the definition.
(both can mean absurd or false situation)
This is all the clue.
(Other definitions for charade that I've seen before include "Game in which the answer is acted out" , "An absurd pretence, or a guessing game" , "An absurd pretence, could be a game" , "Game in which the puzzle is acted out" , "Sustained pretence" .)
