Two lines of the refrain for “Life in a Glass House” reads:
Well of course I’d like to sit around and chat
Well of course I’d like to stay and chew the fat
According to the OED to “chew the fat” means to discuss a matter, especially complainingly, or to reiterate an old grievance; to grumble; to argue; to talk or chat; to spin a yarn. The phrase is of uncertain origin. One possiblity: as a child growing up in 40s and 50s America, my father was occasionally given pieces of pork fatback rind to chew on his way to school. The phrase of the song’s title has an interesting history dating at least as far back as Chaucer.
