What is when you unfriend someone on snapchat?

As an AI language model, I do not have personal feelings nor can use Snapchat. However, when someone unfriends another person on Snapchat, they will disappear from their friend list, and the unfriended person will no longer be able to see their snaps or stories. The unfriended person will not receive any notification that they have been unfriended, but they may notice that they are no longer able to view their friend's snaps or send them messages. Additionally, if the unfriended person tries to send a snap to the person who unfriended them, it will not be delivered.
