This paper brings an ethnographic experience to bear on the existing research field of school bullying, rounding out our understanding by focusing on an essential aspect: children's culture. Based on 14 months of fieldwork and a close analysis of the case of Anat, a 9-year-old victim of bullying, the paper identifies a unique formation of school bullying with no leading bully. Drawing from theoretical approaches which focus on pupils' everyday life, the paper asserts that bullying without a leading bully is rooted in children's culture which effectively enforces bullying as a binding norm by constructing its object as disgusting. The paper explores how disgust shapes school bullying into a collective omnipresent rejection. It also discusses intervention programmes and suggests that within such a social position, one practice to consider would be transferring to a new environment where bullied pupils will not be forced to cope with collectively enforced prejudices.
