Izzy: Eughh that girl has disgusting, long, brown, manky hair.
Sophie: Ewww what a scab ryan.
Izzy: SCAB RYAN?! Not one of those horrible girls who gets with friends' exes and go psycho slating everyone.
Sophie: Yeah, she's one of them. Called me a sket face and Cruella De Ville the other day. She's mental. I hope she never comes near me again.
