Disgusting attack (9)
I believe the answer is:
offensive
I believe this is a double definition.
'disgusting' is the first definition.
('offensive' can be similar in meaning to 'disgusting')
'attack' is the second definition.
(I've seen this before)
(Other definitions for offensive that I've seen before include "Causing resentment or upset" , "Likely to upset" , "Causing anger or annoyance" , "Insulting or repulsive" , "Causing anger or resentment" .)
