Face Book Bully
A Face Book Bully is someone who uses Facebook to annoy you like it's their full-time job. They make fun of you, call you names, and never let you forget how bad you are.
Post: You’re so bad, even your mom is ashamed of you.
Comment: Your face is the worst. I’m going to die watching it.
Message: You’re the worst. I hate you. #facebookbully
