Keep on kissing amorously side by side (4,3,4)
I believe the answer is:
neck and neck
This clue might be a double definition.
'keep on kissing' is the first definition.
(I've seen this before)
'side by side' is the second definition.
(I've seen this before)
'amorously' acts as a link.
I am not very happy about this link. It may belong to one of the definitions.
Can you help me to learn more?
(Other definitions for neck and neck that I've seen before include "keep on canoodling" , "Absolutely level (in race)" , "virtually inseparable" , "Keep on kissing" , "New lovers frequently do it" .)
