They're either arrogant, loud, ditzy or just plain rude? Have you called them out for it too?
Were they damaging to any group work?
Personally, one person sticks out in my mind. Nobody called her out but after she spoke, you'd hear half the class whispering and see them roll their eyes all at once. Working with her on anything was hell. :/
