Playful talk (6)
I believe the answer is:
banter
'playful talk' is the definition.
(I've seen this in another clue)
This is all the clue.
(Other definitions for banter that I've seen before include "Joke in a good-humoured way" , "Humorous ridicule" , "Tease in good-humoured way" , "Action of making use of something" , "Light-hearted chaff or teasing" .)
