look up any word, like blumpkin:
One who follows religiously, but does not participate in "jam sessions" performed by "jam bands." These individuals are often adorned in tie-dyed apparel, hemp accessories, and Birkenstock sandals. The vernacular of such individuals involves such words as "yeah" and "man." Those who are most immersed in "the scene" may have a deep and passionate appreciation for crystals.
BYSTANDER #1: Do you smell a mix of patchouli and trust funds?

BYSTANDER #2: Yeah...a group of jam bandits just passed us. They've apparently been following Yonder Mountain String Band around the country for the last 3 years.
