Make a big noise when closing poetry event (4)
I believe the answer is:
slam
'poetry event' is the definition.
(I've seen this in another clue)
I cannot understand how the rest of the clue works.
Can you help me to learn more?
(Other definitions for slam that I've seen before include "what needs a lot of tricks to succeed" , "Shut violently" , "big contract" , "A grand one is 13 tricks" , "Hit hard" .)
