look up any word, like blumpkin:
singular noun
Any serious fan/follower of The Polyphonic Spree, a jam band of undefined genre whose members (approximately 24 musicians and growing) concenttrate on making music and good feelings rather than money and fame. The band was founded by Tim DeLaughter. This is not a derogatory term.

Any Spreetard worth their salt knows that The Polyphonic Spree is not a cult, in spite of the robes they wear.
