Slapstick projectiles (4)
I believe the answer is:
pies
'slapstick projectiles' is the definition.
(I've seen this in another clue)
This is all the clue.
(Other definitions for pies that I've seen before include "Tarts" , "Pastry snacks" , "Pastry-topped puddings" , "Pastry crusts with fillings" , "food" .)
