Repeatedly cuddle a tight race (4,3,4)
I believe the answer is:
neck and neck
'repeatedly cuddle' is the definition.
I know nothing about this answer so I can't tell whether it can be defined by this definition.
'a tight race' is the wordplay.
I cannot quite see how this works, but
'a' could be 'an' and 'an' is found in the answer.
This may be the basis of the clue (or it may be nonsense).
Can you help me to learn more?
(Other definitions for neck and neck that I've seen before include "being close?" , "side by side" , "Level pegging" , "Keep on kissing" , "New lovers frequently do it" .)
