Chose to drink the last cocktail and get wasted (7)
I believe the answer is:
pickled
'wasted' is the definition.
Both the answer and definition are adjectives. Perhaps there's an association between them I don't understand?
'chose to drink the last cocktail' is the wordplay.
'chose' becomes 'picked' (picking is a kind of choosing).
'to drink' indicates putting letters inside.
'the last' suggests the final letters.
The final letter of 'cocktail' is 'l'.
'picked' going around 'l' is 'PICKLED'.
'and get' is the link.
Can you help me to learn more?
(Other definitions for pickled that I've seen before include "Soused" , "Preserved - drunk" , "Blotto" , "Drunk (as a gherkin?)" , "Preserved in liquid" .)
