n. The practice of wearing a bag over one's body so as to conceal one's physical attributes and force listeners to focus on one's message instead.
Bagism is a term which was created by John Lennon and Yoko Ono as part of their extensive peace campaign in the late 1960s. The intent of bagism was to satirize prejudice and stereotyping. Bagism involved literally wearing a bag over one's entire body. According to John and Yoko, by living in a bag, a person could not be judged by others on the basis of skin color, gender, hair length, attire, age, or any other such attributes. It was presented as a form of total communication: instead of focusing on outward appearance, the listener would hear only the bagist's message.
