Slap on the wrist (4)
I believe the answer is:
cuff
I believe this is a double definition.
'slap' is the first definition.
(I know that cuff is a more specific form of the action slap)
'on the wrist' is the second definition.
(I've seen this before)
(Other definitions for cuff that I've seen before include "Part of a shirt sleeve - hit" , "clout" , "Turned-back hem to sleeve" , "Blow; end of sleeve" , "Smack; end of shirt sleeve" .)
