Distasteful attack? (9)
I believe the answer is:
offensive
I believe this is a double definition.
'distasteful' is the first definition.
(similar in meaning)
'attack?' is the second definition.
(similar in meaning)
(Other definitions for offensive that I've seen before include "Insulting, loathsome" , "Causing anger or resentment" , "Unpleasant - attack" , "Causing anger or annoyance" , "Insulting like aggressive attack" .)
