Drunk when so excluded (3,2,2)
I believe the answer is:
out of it
This clue could be a double definition.
'drunk when' is the first definition.
'out of it' can be an answer for 'drunk' (I've seen this before). I am unsure of the 'when' bit.
'excluded' is the second definition.
(I've seen this before)
'so' acts as a link.
Can you help me to learn more?
(Other definitions for out of it that I've seen before include "is not included" , "Forlorn" , "Without a chance" , "unaware of what's going on" , "Eliminated" .)
