2 questions on chewing

A coupla’ mastication queries:

  1. What is the origin of the term “chewing on the fat”?

  2. Is there truth to the cultural neighborliness in American history of sharing chaw or some form of chewing gum with guests (from the wad of material in the mouth of the host), or is this something history teachers tell their students to gross them out?

Ummm…I’m gonna have to go with the latter.
