“Two portions of meat — and be quick about it!” (4-4)
I believe the answer is:
chop-chop
'be quick about it' is the definition.
I can't tell whether this definition defines the answer.
'two portions of meat' is the wordplay.
'two portions of' shows that letters should be duplicated.
'meat' becomes 'chop' (chop is a kind of meat).
'chop' duplicated is 'CHOP-CHOP'.
'and' is the link.
Can you help me to learn more?
(Other definitions for chop-chop that I've seen before include "Quickly!" , "Hurry up!" , "Get a move on!" .)
