Worthless nonsense (5)
I believe the answer is:
tripe
'worthless nonsense' is the definition.
(I've seen this in another clue)
This is the entire clue.
(Other definitions for tripe that I've seen before include "poor stuff" , "Rubbish (edible, maybe)" , "Lining of the stomach of a cow as food" , "load of rubbish?" , "Rubbish, nonsense" .)
