Bedroom chats about being out of action (4,2,6)
I believe the answer is:
hors de combat
'out of action' is the definition.
('hors de combat' can be a synonym of 'out of action')
'bedroom chats about' is the wordplay.
'about' indicates an anagram.
'bedroom'+'chats'='bedroomchats'
'bedroomchats' is an anagram of 'HORS DE COMBAT'.
'being' acts as a link.
(Other definitions for hors de combat that I've seen before include "Out of action due to injury" , "Disabled, out of the fight" , "Injured and out of action (French)" .)
