Mansonism means: This religious group has Marilyn Manson, the shock-rocker, as its living god. Mansonites are followers of this religion. Marilyn Manson’s concerts are the Mansonites’ place of worship. Another form of worship is to listen to Manson’s music repeatedly and then adapt his lyrics to one’s daily vocabulary. Although there isn’t a set dress code for Mansonites, they tend to wear at least some black. The Mansonites can decide on all aspects of their lives, and are free to abandon the belief system at any time. (in Community Dictionary, added by Frogman)
