U+23CF · emoji since 2015
The eject button is a triangle over a line, the icon for popping out a disc or drive. It means removing, ejecting, and safely taking something out.
Figuratively it tags bailing out and getting out fast, the universal sign for eject, I'm done.
In texting, ⏏️ does not carry a widely used hidden or slang meaning, so you can usually take it at face value. People send it just as it looks, to add a little visual touch or set the mood of a message. Only a handful of emoji have a separate texting code, and ⏏️ is not really one of them.
Its official Unicode name is the Eject Button emoji. In everyday chat most people just call it the eject button emoji or describe what it shows. Copy and paste it from the button at the top of this page.
The ⏏️ leads off a short phrase, and the rest of the words are written in cipher, every letter disguised as another emoji. Tap decipher to reveal the whole line.
