Vodka and orange juice (11)
I believe the answer is:
screwdriver
'vodka and orange juice' is the definition.
(I've seen this before)
This is the entire clue.
(Other definitions for screwdriver that I've seen before include "Cocktail (vodka and 4 down juice)" , "Cocktail of vodka and orange juice" , "Tool used to tighten" , "Drink" , "Common tool" .)
