Spurn, rebuff (6)
I believe the answer is:
refuse
I believe this is a double definition.
'spurn' is the first definition.
(I've seen this in another clue)
'rebuff' is the second definition.
(thesaurus)
(Other definitions for refuse that I've seen before include "Decline, repudiate" , "Don't take the rubbish" , "Decline waste material" , "Decline to accept garbage" , "Decline to jump; rubbish" .)
