U+1F4AF · emoji since 2010
The hundred means full marks: completely true, completely agreed, or completely excellent. It started as keep it 100, slang for keeping it real, and that honesty energy stuck.
People use it to co-sign a take, hype a performance, or stamp something as the genuine article. It's agreement with conviction, not just a nod.
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 Hundred Points emoji. In everyday chat most people just call it the hundred points 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.
