Non-acceptance of absurd earfuls (7)
I believe the answer is:
refusal
'non-acceptance' is the definition.
(I've seen this before)
'absurd earfuls' is the wordplay.
'absurd' indicates an anagram.
'earfuls' is an anagram of 'REFUSAL'.
'of' is the link.
(Other definitions for refusal that I've seen before include "Possibly first option to buy" , "The act of saying no" , "Rebuff" , "regrets?" , "Negation" .)
