Thus two meat-cuts hurry up! (4-4)
I believe the answer is:
chop-chop
'hurry up' is the definition.
(I've seen this before)
'thus two meat-cuts' is the wordplay.
I cannot really see how this works, but
'meat' could be 'chop' (chop is a kind of meat) and 'chop' is present in the answer.
The remaining letters 'chop' is a valid word which might be clued in a way I don't understand.
This explanation may well be incorrect...
Can you help me to learn more?
(Other definitions for chop-chop that I've seen before include "Get a move on!" , "Quickly!" , "Hurry up!" .)
