cult religion started by goddess Vivian (a.k.a. "the only one for Gavin") revolving around the lead singer of the band Bush, Gavin Rossdale. Gavinism contains it's own special language ("ism" language) and it's own list of duties a proper "gavinite" must perform to be "worthy" of this religion (ex. only buy products that contain glycerine)
