to shoot the breeze, to make small talk
Não tinha nada para fazer, fiquei jogando conversa fora com a Rita.
I had nothing to do, I was shooting the breeze with Rita.
The image turns on the verb jogar fora, "to throw away". A conversa fora is talk with no aim — not meant to settle anything, just enjoyed for its own sake — so it is light enough to be "thrown out".
