Humbug; tripe (8)
I believe the answer is:
nonsense
This clue is a double definition.
'humbug' is the first definition.
(I've seen this in another clue)
'tripe' is the second definition.
(I've seen this before)
(Other definitions for nonsense that I've seen before include "Boloney, tosh" , "Bunk" , "Rubbish, drivel" , "Piffle and poppycock" , "Rubbish, foolish talk" .)
