A group of girls were 'bullying' [='picking on'] her at the playground.
She uses her position as a famous actress as a 'bully pulpit'.
My sister was the school/class/neighborhood 'bully'.
(..) - BILLY: Janet! - JANET: Billy. I missed you. Hey, guys, I missed you. So, have any of you ever been bothered by a bully? Pete, at school. He's always picking on Billy. And, dear, tell me, what do you do when that happens? (STAMMERS) They stick up for me. Good, because the spirit in this house - is a lot like that bully. - Yes. ED: And he's got it in for Janet. So you guys gotta stick up for her, the same way they stick up for you. Family sticks together. (..)2016 The Conjuring 2
