Kiss someone inflicting punishment? (7)
I believe the answer is:
smacker
'kiss' is the definition.
(I know that smacker is a type of smack)
I can't explain the rest of the clue.
Can you help me to learn more?
(Other definitions for smacker that I've seen before include "pound" , "Loud kiss - GBP1" , "someone taking part in strike?" , "Loud kiss -- PS1" .)
