Spook

Boo! A white, cartoon ghost making a silly face. Its tongue is stuck out and arms are outstretched, as if trying to scare someone in a friendly way. Several platforms feature one larger, bulging eye, while others show the ghost winking.

Resembles a classic ghost costume for Halloween. May also be used to convey something or someone is fun or goofy. Thanks to its raised arms, some use this emoji as a way of expressing an excited Yay!

May also be used to refer to the slang term "ghosting", where a personal relationship is ended suddenly without explanation by one person withdrawing from all communication with another.

Samsung's design previously depicted this as a smiley in a ghost costume.

This emoji predates the inclusion of emojis within Unicode. It was first added to early Japanese emoji keyboards by Softbank in 1999.
