This was the "anti-Frat" fraternity in the early 70's, membership consisted of owning a poster of Frank Zappa sitting on a commode smoking a joint
"Our fraternity - Phi Zappa Crappa - required no dues, had no house, enforced no rules, and was a loose knit group. We were united in the anti-Fraternity movement."
