Fangirl

A person who is obsessed with a band, artist, book or movie. He or she can talk about it endlessly. Most of the time they have a huge cruh on one ( or more ) of the member or characters and they spend their time till late at night on social media like twitter, tumblr or instagram so that they won't miss anything that there will be posted.

A fangirl is more than just a fan who likes something. They dedicated their life to it, it became a lifestyle.

Peson : "Wow, you're such a fangirl"
