A person who only messages you on Facebook and acts like they don't know you in real life. They just want your friend request for no reason.
"Hey, I saw your profile. Are you my friend?", while ignoring your face at school.
"You're on Facebook? Let's be friends.", even though we sat next to each other in math.
"I'm sending you a message. Don't talk to me in person.", because that's too much work.
