President raves, typically about mockery (8)
I believe the answer is:
travesty
'mockery' is the definition.
(I know that mockery can be written as travesty)
'president raves typically about' is the wordplay.
'about' indicates the answer is hidden within the clue (the clue goes around or about the answer).
'TRAVESTY' is hidden in the letters of 'president raves typically'.
(Other definitions for travesty that I've seen before include "Total misrepresentation" , "Grossly unfair representation" , "False or distorted representation of something" , "Absurd representation" , "Grotesque distortion" .)
