Generate weird drink (5,3)
I believe the answer is:
green tea
'drink' is the definition.
(type of tea)
'generate weird' is the wordplay.
'weird' is an anagram indicator.
'generate' is an anagram of 'GREEN TEA'.
(Other definitions for green tea that I've seen before include "Beverage" , "Hot drink - teenager (anag)" , "brew-up?" , "Colourful drink for teenager" , "Infused drink" .)
