Get a move on in pair of boots? (4-4)
I believe the answer is:
chop-chop
'get a move on' is the definition.
(phrase used to tell someone to hurry up)
'pair of boots?' is the wordplay.
'pair' indicates the doubling of some letters.
'of boots?' becomes 'chop' (I am not sure about this - if you are sure you should give a lot more credence to this answer).
'chop' doubled is 'CHOP-CHOP'.
'in' is the link.
Can you help me to learn more?
(Other definitions for chop-chop that I've seen before include "Hurry up!" , "Get a move on!" , "Quickly!" .)
