Poetry event (4)
I believe the answer is:
slam
'poetry event' is the definition.
(I've seen this in another clue)
This is all the clue.
(Other definitions for slam that I've seen before include "Ambitious contract" , "Shut (door) with force" , "big contract" , "Violently strike against" , "Severely criticise; shut (a door) forcefully" .)
