Impossible bottle party? (2,3,2)
I believe the answer is:
no can do
'impossible' is the definition.
('no can do' can mean something is impossible)
'bottle party?' is the wordplay.
I cannot quite understand how this works, but
'party?' could be 'do' (do is a kind of party) and 'do' is found in the answer.
This explanation may well be incorrect...
(Other definitions for no can do that I've seen before include "Nothing manageable" , "off-putting response" , "Can't manage it, see doc anon" , "Absolutely not!" , "That's out of the question!" .)
