Piggybacks are a series of moments you create with friends, and a new way to be part of each other's day.
How it works:
1) Start a piggyback by taking a video or photo.
2) Friends see it in their feed and can reply using their camera.
3) As you all keep adding to it, the piggyback grows into an awesome, hilarious, open conversation any of your friends can jump in on - then it disappears by the end of the day.
