Cocktail stirrer (7,5)
I believe the answer is:
swizzle stick
'cocktail stirrer' is the definition.
(I've seen this before)
This is the entire clue.
(Other definitions for swizzle stick that I've seen before include "It's used to take the fizz out of drinks" , "Champagne stirrer" , "Rod used to stir an effervescent drink" , "Drink stirrer" , "Cocktail stirrer" .)
