As with Pinocchio, the nose becomes longer with each lie, which exposes him as a liar. Symbol of a falsehood, boast, or an unlikely story.
The lying face emoji was introduced in 2016 and released as part of the Unicode 11.0 standard. This emoji can be found under the smileys and emotions
category. Because the lying face emoji has been around for quite some time, it should display correctly in the majority of operating systems.
