or ghost emoji [gohst ih-moh-jee]
What does 👻 mean?
The ghost emoji depicts a cartoonish looking figure in white, shaped like a teardrop or bubble with arms and round black spots for eyes.
It usually pertains to scary things and, of course, to Halloween. In texting, it can mean that someone is not feeling like themselves, they are feeling inconsequential or invisible; it can mean, "hey boo," and it can mean the texter finds something to be surprisingly creepy.

Where does come from?
Don’t be haunted by the many ways the ghost emoji is used! Ghosts represent all kinds of things—the past, the unknown, people who have died, people who want to be invisible, premonitions or “feelings,” paranormal events, and more. There are even a whole bunch of words for the … thing: specter, spirit, spook, ghoul, phantasm, apparition, wraith, and poltergeist, to name a few.
So basically we needed the ghost emoji … bad. It was approved as part of Unicode 6.0 in 2010 and added to Emoji 1.0 in 2015. In most platforms, it’s shown smiling, and, for some reason, it’s tongue is usually hanging out. The Google ghoul is actually winking, and the Emojidex ghost is the only one that is dark and ghoulish … boo!
