Drink-offering (8)
I believe the answer is:
libation
I believe this clue is a double definition.
'drink' is the first definition.
(libation can humorously mean a drink)
'offering' is the second definition.
(I've seen this before)
(Other definitions for libation that I've seen before include "offering of wine" , "Alcoholic drink" , "Ritual of pouring wine as sacrifice to a god" , "A serving of an alcoholic beverage" , "Drink poured out as offering to God" .)
