Deliberately causing annoyance (11)

I believe the answer is:
provocative
'deliberately causing annoyance' is the definition.
(I've seen this before)
This is all the clue.
(Other definitions for provocative that I've seen before include "Designed to cause anger or arousal" , "Deliberately annoying" , "Deliberately aimed at causing a strong reaction" , "Exasperating" , "Aggravating" .)
