Are you the kind of person that can be trusted by a family, close friend, or special someone when they tell you a secret? Confirm it by using the Zipper-Mouth Face emoji ????.
This emoji has a simple yellow face that has an open eyes and closed zipper for the mouth as if it is saying that “Your lips are sealed.” It was in 2015 when it has become a part of the Unicode 8.0.
You can use the Zipper-Mouth Face emoji ???? to tell the other person to stop talking, too, because you need silence.
