Brainstorm

Hi everyone!
I'm writing a book called, "The Snobs". It's about this girl who goes to school with her best friend, Amanda, and they have to deal with bully problems. There are three bullies. They are all rich, snobby, and mean. One bully, Joyce, is the head bully. She make nice comments, but doesn't really mean them. The other bully, Taren, has a habit of saying the word, "Like", a lot and she is an expert at spreading mean rumors. The last bully, Cait, is a more physical bully. She prefers breaking glasses, pushing people into mud, kicking, punching, etc.
I need ideas of what mean things the bullies can do to make the story more interesting. The main character, Angela, already got her hair cut by the bullies against her will. Her hair is a mess and it's really short.
Please post a comment on what the bullies can do to make Angela and Amanda upset. I'm out of ideas.
Love,
Kate:)
