Why does typing :O turn into an unusable, unrelated emoji?

[Android Central Question]

Typing :O in Messaging causes it to be replaced with a short, green devil face with a smile. It doesn't match the face, other smileys don't turn into emojis, and I can't find this emoji anywhere on my keyboard

That is a really weird bug. Can you explain which messaging app you are talking about?

Sounds like someone is pranking you. Is it possible they have created a shortcut when you type the O it turns to the emoji?
