Comes from being called that when traveling through the Mid West of the U.S. in the late 1960's because Significant Other had a pony tail and I wore a colorful dress. It was that or being called Communnists just because of how we dressed. Anyway, most gas station across that section, wouldn't give us service except in Iowa where, for some reason, people were very friendly. Thank you Iowa for being nice to a couple of kids who just wanted to see the country.
Like this thread. It's interesting to see where everybody chose their name from.
