While the The Fault in Our Stars adaptation starring Shailene Woodley is set to take over the box office this weekend, fans are practically more excited to see John Green than the film’s actors.

He has a whole legion of fans who call themselves Nerdfighters who have their own hand signs. They’ll also tell you to give some props to John Green’s brother Hank Green. What’s going on with John Green is more than just an awesome tearjerker of a YA novel and movie, it’s a movement.
