'abrupt withdrawal from' is the definition.
I can't judge whether this defines the answer.

'bitter game' is the wordplay.
'bitter' becomes 'cold' (similar in meaning).
'game' becomes 'turkey' (I can't explain this - if you can you should believe this answer much more).
'cold'+'turkey'='COLDTURKEY'
