Walked casually, topless: deliberately caused provocation (7)

I believe the answer is:

trolled

'deliberately caused provocation' is the definition.

'walked casually topless' is the wordplay.
'walked casually' becomes 'strolled'.
'topless' means to remove the first letter.
'strolled' with its first letter taken off is 'TROLLED'.

(Other definitions for trolled that I've seen before include "Made provocative comments" , "posted offensive comment" .)

I've seen this clue in The Everyman puzzle in The Observer.
