They cannot be killed. They only come back stronger. Zombies? No: Emoticons, which Facebook added to its chat feature for desktop users.

Facebook announced the addition in a post on its Facebook Tips page:

You can now easily add smiley faces and other emoticons to a conversation when you’re chatting with your friends. Look for the icon in the bottom-right corner of your chat window and emote away.

The ever-present like button also makes an appearance, as the very last emoticon depicts the familiar thumbs-up.

TechCrunch pointed out that Facebook users can still add emoticons that aren’t on Facebook’s list of 21, such as :-* to add a kiss, or adding any user’s name in double brackets to incorporate their profile picture into the chat.

Emoticons have not yet been added to Facebook messages or its mobile applications.
