Tied down repeatedly (4,3,4)
I believe the answer is:
neck and neck
'down repeatedly' is the definition.
(I've seen this before)
I cannot understand how the rest of the clue works.
Can you help me to learn more?
(Other definitions for neck and neck that I've seen before include "Keep on kissing" , "being close?" , "Level pegging" , "Bill and coo" , "New lovers frequently do it" .)
