When you reach a point in your spiritual life of enlightenment..you "give it away" meaning pass on that knowledge to your family and friends on order to lead them to the source.
An imaginary store like a Goodwill where hand-me-down items can be bought so for so cheap, it's like the proprietor of the business is giving the stuff away. The phrase is used by school kids in L.A. to make fun of the possessions of poorer students, who may wear used or non name brand clothing and shoes. This may be attributed to parents who could not afford to buy nice shoes and/or apparel for their children.
