Amish friendship bread
a hoax foisted upon unsuspecting, well-meaning, liberal, suburbanites by the Ziploc company; which distributes instructions for reproducing a sweet yeast bread culture requiring the utilization of multiple large Ziploc bags, depending upon an unreasonably romantic notion of the pure goodness of rural Amish folk, and spread by the directive that this virus be passed on to four friends in the fashion of an email virus.
"My best friend at work just gave me a Ziploc bag full of squishy yeast with instructions for making Amish friendship bread-- what the heck am I supposed to do with this?"
