Common misused emojis include:
The Love Hotel – It looks like a building with a H on the front, and a pink heart to the side, which some people have used to represent a caring hospital, or possibly a symbol for "home is where the heart is,” but the truth it's the symbol for a hotel that rents rooms by the hour for trysts.
Cooking – The frying pan with an egg emoji is often used to convey just that, frying an egg, but the reality is it’s meant to represent cooking in general.
Dizzy –The star at the end of a crescent light is often used to represent a shooting star, but it’s actually there to represent the feeling of being dizzy.
Proud – That round face with steam blowing from the nostrils is most likely used to represent angry, but it actually represents proud, but not in the good way. Instead it means “proud and disdainful" as in "I'm right and you're wrong."
Relieved – That face with what looks like a tear on one side isn’t supposed to be used to express sadness or being upset, instead it’s actually a sad but relieved face.
Openness – You may have used the two hands side by side with the palms facing outward emoji to say “whatever,” but in truth it’s supposed to represent openness.
Sassy Woman – That cheerful looking woman raising one outstretched palm isn’t actually the sassy gal as you may think. It’s actually part of the information desk person's emojis and represents a women who’s here to help you.
