Get moving to improve method of seduction (4,2)
I believe the answer is:
come on
'improve method of seduction' is the definition.
'come on' can be an answer for 'improve' (thesaurus). I'm not sure about the 'method of seduction' bit.
'get moving' is the wordplay.
'get' becomes 'come' (synonyms).
'moving' becomes 'on' (I can't justify this - if you can you should give a lot more credence to this answer).
'come'+'on'='COME-ON'
'to' acts as a link.
Can you help me to learn more?
(Other definitions for come on that I've seen before include "Sexy remark" , "You must be joking!" , "Develop - hurry up!" .)
