Ginger __ (4)
I believe the answer is:
snap
'ginger' is the definition.
(I've seen this in another clue)
This is all the clue.
(Other definitions for snap that I've seen before include "Picture" , "Speak irritably; photo" , "on the spur of the moment" , "Go to pieces < , it's said, quickly" , "game of cards" .)
