Flying reptiles getting cold drink (6,3)
I believe the answer is:
triple sec
'drink' is the definition.
(triple sec is a kind of drink)
'flying reptiles getting cold' is the wordplay.
'flying' indicates anagramming the letters (letters fly around into new positions).
'getting' means one lot of letters go next to another.
'cold' becomes 'C' (eg on taps).
'reptiles' with letters rearranged gives 'triplese'.
'triplese'+'c'='TRIPLE SEC'
(Other definitions for triple sec that I've seen before include "alcohol" , "Strong orange-flavoured liqueur - perils etc (anag)" , "Drink" .)
