Sailors getting in the booze (8)
I believe the answer is:
absinthe
'booze' is the definition.
(absinthe is a kind of booze)
'sailors getting in the' is the wordplay.
'sailors' becomes 'abs' (AB is short for able seaman).
'getting' is a charade indicator (letters next to each other).
'abs'+'in'+'the'='ABSINTHE'
(Other definitions for absinthe that I've seen before include "Bitter liqueur" , "Aniseed flavoured liqueur" , "Aniseed-flavoured liqueur" , "Strong green alcoholic drink" , "Strong liquour in the basin?" .)
