Scrap rare old whiskey
I believe the answer is:
row
'scrap' is the definition.
(I've seen this in another clue)
'rare old whiskey' is the wordplay.
'rare' becomes 'r' (listed by Oxford Dictionary of Abbreviations).
'old' becomes 'o' (common abbreviation eg in OE for Old English).
'whiskey' becomes 'W' (alpha bravo charlie delta ...).
'r'+'o'+'w'='ROW'
(Other definitions for row that I've seen before include "Barney - rank" , "Fight in a queue?" , "bank?" , "Angry dispute" , "Paddle" .)
