Nonsense, bunk (5)
I believe the answer is:
hokum
I believe this is a double definition.
'nonsense' is the first definition.
(hokum can mean nonsense or rubbish)
'bunk' is the second definition.
(I know that bunk can be written as hokum)
(Other definitions for hokum that I've seen before include "Claptrap" , "gammon" , "Rubbish" , "Hogwash" , "Be extremely good (at activity)" .)
