It is a verb, used in general conversation, in informal conversation. It refers to the act of talking, often rubbish, merely to pass time.

It draws its meaning from the drawn out process of chewing fat from a steak, as it is often a pleasurable experience since it tastes amazing, but also takes up time.
"The bus doesn't come for two hours."

"I guess we'll just chew the fat then."
