Gossip, having poured out our drink (3)
I believe the answer is:
rum
'drink' is the definition.
(rum is a kind of drink)
I cannot understand how the remainder of the clue works.
Can you help me to learn more?
(Other definitions for rum that I've seen before include "Odd like drink distilled from molasses" , "Pirate's grog" , "An alcoholic spirit - sounds odd" , "Odd spirit from sugar cane" , "Odd, like sailor's drink" .)
