Potter Poser 

One who pretends to be the biggest Harry Potter fan in the world, when in all reality they have only seen the movies and have not read the books.

Person 1: AHH!! Harry Potter!! I love Harry Potter!! YAY YAY YAY!! NEW MOVIE!!!
Person 2: Shut up. You don't even know what a Horcrux is.
Person 1: Who cares! I love me my HP!
Person 2: Ya stupid Potter Poser

People who reshare your facebook post but did not acknowledge it by liking it

I have a friend, he is a poser poster. He keeps resharing my posts on Facebook because they are good but has never "Liked" it out of decent courtesy.
