It’s what happens when people get together for a celebration, analysis, and discussion of girlcanon - those often overlooked and derided books or other media that were especially prized by young girls and teenagers. It doesn’t matter if you identify now or ever as a girl; what matters is girlcanon.
Horse books! The Twilight series! Shoujo manga! Labyrinth! Anne of Green Gables! Jem and the Holograms! Early Victorian fairy tales, mid 19th century boarding school books or late 20th century boybands - if girls loved it, and people laughed at them for loving it, it belongs.
To hold a GirlyCon, have a sleepover, a party, an evening get together, a weekend retreat at your house and invite a bunch of people. Do readings out loud of various girlcanon books and then have discussions. Do weird craft projects, write fic, have quiet reading time, and swap books. Or whatever!
Then tell us all about it! We have a Dreamwidth community for making your GirlyCon reports and discussing girlcanon, a Resource centre suggesting some girlcanon lists and how-tos, an FAQ explaining what GirlyCon is (and is not).
GirlyCon can be anywhere, at any time. It can be critical, or celebrational, or just an awesome party with cocktails named after book characters.
GirlyCon, like literature for girls, has myriad possibilities.
