Get some wine, or lose it (3,3)
I believe the answer is:
see red
'lose it' is the definition.
(I've seen this before)
'get some wine' is the wordplay.
'get' becomes 'see' (I've seen this in other clues).
'some wine' becomes 'red' (red wine is a kind of wine).
'see'+'red'='SEE RED'
'or' is the link.
(Other definitions for see red that I've seen before include "Get furious" , "Lose the head as bull might" , "Burst a blood vessel" , "Become suddenly angry" , "Lose temper as bull might" .)
