As featured in the app’s promo video below and noted in our original review of the app:
The thing that makes Slingshot unique is the reply feature. In order to view a sling that you’ve received, you will need to send one to that person to unlock it. This is pretty cool, as it encourages both parties to use the app constantly, in order to keep the conversation going. As you view a sling that was sent to you, there is even the ability to quickly record your reaction and sling it back to them.

But in the new version of Slingshot, locked shots are now optional. As pointed out by Facebook in the release notes of the latest update to the app:
Sling a shot to see a shot? Not necessarily! After shooting a photo or video, now you can choose whether to sling it as a locked or unlocked shot.
The latest update to Slingshot also includes additional bug fixes.
