Usually a boy who makes you feel special. He makes you feel like you are the only girl in his life, when really you are just one in 100.
They flirt with other people, not just you. They talk to you all day, then the next day they ignore you. They send you mixed messages, and your not sure whether he likes you or not?
You can't keep your mind off him, even though you know your nothing to him.
He is such a player.
