GI and General sloshed: it's the drink (6,3)
I believe the answer is:
ginger ale
'the drink' is the definition.
(ginger ale is a kind of drink)
'gi and general sloshed' is the wordplay.
'and' is a charade indicator (letters next to each other).
'sloshed' indicates anagramming the letters.
'general' is an anagram of 'ngerale'.
'gi'+'ngerale'='GINGER ALE'
'it's' is the link.
(Other definitions for ginger ale that I've seen before include "One drink" , "It won't make you drunk!" , "Spicy, sweetened non-alcoholic drink" , "Fizzy drink" , "pop" .)
