Confabulate (4,3,3)

I believe the answer is:
chew the fat
'confabulate' is the definition.
(thesaurus)
This is the entire clue.
(Other definitions for chew the fat that I've seen before include "Shoot the breeze?" , "Argue incessantly" , "Gossip, chat" , "Indulge in idle conversation" , "Mistress Sprat liked to?" .)
