Kiss someone inflicting punishment? (7)
I believe the answer is:
smacker
'kiss' is the definition.
(smacker is a kind of kiss)
I don't understand the remainder 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" .)
