Quick stick (4)
I believe the answer is:
poke
'quick stick' is the definition.
(I've seen this in another clue)
This is all the clue.
(Other definitions for poke that I've seen before include "bag" , "Ridicule - . . . . fun at" , "Jab or prod" , "Jab - old type of bonnet" , "Thrust forward; sack" .)
