B button (blood type) Emoji

Symbols

A vibrant red square containing the bold white capital letter 'B'. It mimics the look of a physical button or an indicator light found on control panels.

Usage Context

While originally designed to denote blood type B, it gained massive popularity in internet culture as a way to replace the letter 'b' in words for comedic effect or to signal irony. It is frequently paired with other letter buttons like 🅰 or 🅾 to create custom text-based messages or signatures.

History

Included in Unicode 6.0 in 2010, the B button was originally intended for medical identification in Japanese digital messaging services, where indicating blood type is a common cultural shorthand for describing personality traits.
