Drinks shot (5)
I believe the answer is:
round
This clue is a double definition.
'drinks' is the first definition.
(I've seen this before)
'shot' is the second definition.
(thesaurus)
(Other definitions for round that I've seen before include "Like ball < in rough" , "Description of Tweedledum" , "Get applause" , "A partsong in which voices follow each other" , "Number of drinks bought together" .)
