The keycap five is the number 5 on a button. It means five stars, high fives, five-minute warnings, and halfway to ten.
It rates the things you love, counts down launches, and marks the famous five more minutes of sleep.
In texting, 5️⃣ 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 5️⃣ is not really one of them.
Its official Unicode name is the Keycap 5 emoji. In everyday chat most people just call it the keycap 5 emoji or describe what it shows. Copy and paste it from the button at the top of this page.
The 5️⃣ 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.
