Enthusiastic kisses or corporal punishment (6)
I believe the answer is:
smacks
'enthusiastic kisses' is the definition.
'smacks' can be an answer for 'kisses' (smack is a kind of kiss). I am not sure about the 'enthusiastic' bit.
I don't understand the remainder of the clue.
Can you help me to learn more?
(Other definitions for smacks that I've seen before include "Smells; fishing boats" , "Strikes with the hand" , "Hits the fishing vessels" , "Slaps; flavours; boats" , "Has a hint (of)" .)
