Cut buns to pieces! (4)

I believe the answer is:

snub

'cut' is the definition.
(synonyms)

'buns to pieces' is the wordplay.
'to pieces' indicates anagramming the letters (the same pieces in a new order).
'buns' is an anagram of 'SNUB'.

(Other definitions for snub that I've seen before include "Rebuff humiliatingly" , "Slight - short and blunt - humiliation" , "Check" , "Reject a person with cold behaviour" , "unusually short" .)

I've seen this clue in the Evening Standard.
