sio

Sio is a term relatively used by high schoolers on social media. It means "school is out", and is often used on Snapchat when users send mass snapchats for streaks after getting off school.

Luke just sent out a snap saying "s/r sio" to all of his stories, streaks, and recents. He must be out of school now
