"general unspecified free food"

This is a cooperative term originated in the Ann Arbor Student Cooperatives, specifically in the Michigan House.

Though the term originated to refer to food, it is now expanded to anything that is available for use by anyone, for example, food, blankets, books, and penises.
Hey, are these cookies guff?
