Jackie Mathews and Alison Peters, known as the Bummer Twins, are students at Georgia's school. Georgia says they are common and tarty girls. In Angus, Thongs and Full-Frontal Snogging, they begin these new fads and make everyone go along with them. These shenanigans include levitation, guarding a park loo while she changed out of her uniform, grading other girls for physical attractiveness, and learning to make yourself faint. Georgia finally stands up to them and the entire school ends up talking about it.
