Rude or surly (8)
I believe the answer is:
churlish
I believe this is a double definition.
'rude' is the first definition.
(thesaurus)
'surly' is the second definition.

(Other definitions for churlish that I've seen before include "Ill-natured, boorish" , "Rude and surly" , "Mean-spirited and surly" , "Ill-mannered and surly" , "Uncouth" .)
