Two couples playing game stirred drinks (5,7)

I believe the answer is:
mixed doubles
'two couples playing game' is the definition.
I can't tell whether this defines the answer.
'stirred drinks' is the wordplay.
'stirred' becomes 'mixed' (I've seen this in another clue).
'drinks' becomes 'doubles'.
'mixed'+'doubles'='MIXED DOUBLES'
Can you help me to learn more?
(Other definitions for mixed doubles that I've seen before include "Tennis competition" , "Woman/man v woman/man at tennis" , "tennis match?" , "shorts?" , "His 'n' hers tennis" .)
