In the US, the B button emoji went down a completely different path. The Los Angeles-based street gang, the Bloods, have been known to change words with the letter C, the first letter of their rival gang the Crips, to Bs (e.g., boolin‘ ( cooling) and Bompton ( Compton)). People there took to the B button emoji to communicate their blood type on social media, especially in dating and romantic contexts.

In East Asian countries like Japan, there is a popular belief that a person’s blood type influences their personality, character, and compatibility with others. It was originally intended to represent the blood type B alongside A (🅰️), AB (🆎), and O (🅾️) because you totally need to represent your blood type in emoji form all the time, right? Across platforms, it appears as a white, capital letter B on a red square. The Unicode Standard officially calls 🅱️ the negative squared Latin capital letter B emoji, but it’s commonly referred to as the B button emoji, a much more convenient name … because seriously that’s a long name.ī button emoji was approved under Unicode 6.0 in 2010.
