When contracting all your face muscles at once in the hope that the person who witnesses it will never communicate with you again!
The witch Bianca threatened Rahhman by telling him to "shush your face" so Rahhman called the witch's bluff, and shushed his face in front of her in the attempt that he would never have to talk to her again. Unfortunately, it was just a dream, Rahhman never shushed his face to the girl that loves him the most and to this day Rahhman and Bianca share a very poisonous friendship that will carry on happily ever after.
Get the Shush your face mug.
