Talk with drink is a hit (6,5)
I believe the answer is:
rabbit punch
'a hit' is the definition.
(I've seen this before)
'talk with drink' is the wordplay.
'talk' becomes 'rabbit' (rabbit can informally mean to talk).
'with' says to put letters next to each other.
'drink' becomes 'punch' (punch is an alcoholic drink).
'rabbit'+'punch'='RABBIT-PUNCH'
'is' acts as a link.
(Other definitions for rabbit punch that I've seen before include "hit" , "Sharp chop to the back of the neck" , "It may knock you out" , "What causes a pain in the neck" , "Blow to back of neck" .)
