Rebuff and return the rolls (4)
I believe the answer is:
snub
'rebuff' is the definition.
(synonyms)
'return the rolls' is the wordplay.
'return' says the letters should be written backwards.
'the rolls' becomes 'buns' ('bun' can be a synonym of 'roll').
'buns' back-to-front is 'SNUB'.
'and' is the link.
(Other definitions for snub that I've seen before include "Spurn; (of nose) turned up at the end" , "Blank" , "Ignore, spurn disdainfully" , "Rude rejection" , "Rebuff with buns" .)
