Verbal abuse has been identified as a common element in the life of children in school. This paper explores how this discursive practice is used in the construction of masculinities and femininities among children aged 14-15 through observations and interviews in classes in two schools in Stockholm. Verbal abuse, often with sexual content, contributed to "toughness", a central component of hegemonic masculinity in the schools. Popular, tough boys generated most of the verbal abuse, but were not necessarily regarded as verbally abusive; rather, responsibility for the bulk of verbal abuse was attributed to "rowdy" boys. Girls' verbal abuse was not similarly advantageous for their femininity; instead, both through being verbally abusive and being the target of abuse, girls risked being positioned negatively. It appears that verbal abuse in school simultaneously orders masculinities and femininities, and structures heterosexual relations between the genders. (Contains 4 notes.)
