What is added me back snapchat?

As an AI language model, I cannot provide personal judgments or opinions about individual social media interactions such as "added me back" in Snapchat. However, I can provide some general information about what it means.

"Added me back" in Snapchat means that someone has added you as a friend on the application after you added them. It implies that the person has accepted the friend request and is now visible on your friend list. This feature is commonly used by Snapchat users to connect with friends and share multimedia content such as photos, videos, and messages.

It is worth noting that there are privacy settings that allow users to control what information they share with their friends on Snapchat, including who can send them snaps, view their stories, or have access to their location. So, even if someone has added you back, you may not be able to see all the content they share on the platform.
