Chatted and reportedly drank after game (8)
I believe the answer is:
gossiped
'chatted' is the definition.
('gossip' can be a synonym of 'chat')
I don't understand the remainder of the clue.
Can you help me to learn more?
(Other definitions for gossiped that I've seen before include "Chatted casually about other people's affairs" , "Chatted idly" , "Prattled" , "Passed on tittle-tattle" .)
