The B button: a blood-type symbol that the internet turned into a joke and never gave back.
Unicode created 🅱️ to represent blood type B on Japanese phones, where blood type is a personality shorthand like a star sign. Western internet culture ignored that completely and repurposed it in 2018 as a letter-substitution meme. Today it survives as ironic, deliberately dated humor rather than a symbol with a fixed meaning.

These are the real emoji characters — tap one to copy it, then paste anywhere. Because they’re text, they show up as emoji wherever you send them.
In practice 🅱️ is a tone marker, not a word. Its main job is letter substitution: you replace a B (or any consonant that's close enough) with the emoji — 🅱️ruh, 🅱️ozo, 🅱️ig mad, 🅱️ased — and the sentence instantly reads as unserious. Sent alone it functions as a shrug or a punchline you can't be bothered to write, roughly "lol, nothing to add." Repeated as 🅱️🅱️🅱️ it becomes pure noise, the typed equivalent of a dumb face. There is a second, literal reading that still matters: on Japanese and Korean apps, and in health or anime contexts, 🅱️ genuinely means blood type B, often tied to a personality stereotype (independent, stubborn, does their own thing). Which reading applies is almost always obvious from the language of the chat.
Almost always letter substitution: swap a word's first letter for 🅱️ (🅱️ruh, 🅱️ozo, 🅱️ig mad) to mark the sentence as unserious. Sent bare with no word attached, it reads as a shrug — acknowledgment with nothing behind it.
Lives on as deliberately dated humor. 🅱️ in a caption or comment flags the post as ironically cringe or old-internet. Gen Z uses it the way millennials use Impact-font memes — the joke is that it's expired.
Story text and comment roasts. A row of 🅱️🅱️🅱️ under a friend's post is affectionate mockery, not praise. On close-friends stories it's basically keyboard mashing with extra attitude.
A humor filter more than a signal. Someone opening with 🅱️ruh is testing whether you speak fluent irony. It reads young and very online; it does not read as flirty, and it rarely survives past the first few messages.
Only safe in an established joke channel. In a client thread or DM to a manager, 🅱️ looks like a typo, an accidental keycap, or a shrug at a serious request. Blood-type contexts aside, keep it out of anything with stakes.
If a girl sends you 🅱️, read it as playful, not romantic. It's a joke marker: she's teasing you, softening a roast, or telling you the last message was stupid in a fond way. 🅱️ruh or 🅱️ozo aimed at you is banter between people already comfortable with each other, closer to shoving your shoulder than flirting. It carries almost zero sincerity, so don't mine it for hidden interest. The signal it actually sends is about her humor — very online, ironic, comfortable with dated memes — not about how she feels about you.
B Button (Blood Type) 🅱️ and AB Button (Blood Type) 🆎 look closely related and get swapped constantly, but they land differently in a message. Here is what separates them, so you send the one you actually mean.
Officially blood type B, but hijacked into a letter-substitution meme. In English chats it's a tone marker for ironic or deliberately dumb humor and almost never means blood type.
Blood type AB from the same Japanese keypad set. It never got memed, so it's still read literally — health posts, anime personality references and bios. Sending it as a joke rarely reads as one.
It’s the same character everywhere — each platform just draws it in its own style. Here are three open emoji sets side by side, plus how your own device renders it:
| Platform | How it differs |
|---|---|
| Apple | White bold B on a rounded red-orange square. The most-recognized version and the one the meme was built on. |
| Flatter red square with a white B and slightly tighter corners; nearly identical in meaning, marginally less punchy at small sizes. | |
| Samsung | Deeper red with a thicker, more geometric B. Older One UI builds used a lighter shade that can look pink in dark mode. |
| Microsoft | Historically a red rounded square with a serif-ish B; on some Windows builds the letter renders thin enough to be mistaken for an 8 at small sizes. |
| Bright red square, high contrast, very legible inline — reads clearly even inside a wall of text. | |
| Twemoji shows a muted brick-red square. Slightly desaturated, which softens the shouty effect the joke usually relies on. |
Apple, Samsung and WhatsApp draw their own proprietary versions, which we don’t redistribute — the notes above describe how they differ. Open sets shown under their licences: Twemoji (CC-BY 4.0), Noto Emoji (Apache 2.0), OpenMoji (CC BY-SA 4.0).
The b emoji 🅱️ is not always read the way you intend it. These three situations change what 🅱️ signals, and knowing them keeps you from sending the wrong message.
Quick answers to what people ask most about the b emoji 🅱️ — what it means in a text, who tends to send it, and how to copy it onto your own keyboard.
🅱️ is officially the B Button (Blood Type) emoji, representing blood type B. In English-language internet use it carries no literal meaning — it's swapped in for a word's first letter, as in 🅱️ruh, to mark the message as a joke or deliberately stupid.
From a girl, 🅱️ is playful teasing, not flirting. It marks the message as unserious — softening a roast, mocking something dumb you said, or just adding noise. It signals an ironic, very-online sense of humor rather than any romantic interest.
No. 🅱️ has no gang meaning. It was encoded in Unicode 6.0 to represent blood type B on Japanese carriers. A 2018 wave of jokes loosely linked it to the Bloods, but that association is meme humor, not an actual coded signal.
Copy 🅱️ from this page, or type :b: on Slack and Discord to auto-convert it. On iPhone and Android, search "B" or "blood" in the emoji keyboard — it appears under Symbols alongside 🅰️, 🅾️ and 🆎.
It started as a 2018 meme where users substituted 🅱️ for consonants in words, producing 🅱️ruh and 🅱️ozo. The substitution makes text look absurd and low-effort on purpose, which became the joke. It now signals deliberately dated, ironic humor.
🅱️ represents blood type B; 🆎 represents blood type AB. Both come from the same Japanese blood-type keypad set. Only 🅱️ picked up meme status — 🆎 is still used almost entirely at face value, in health, anime and profile contexts.
Only ironically. Using 🅱️ sincerely reads as out of touch, but using it because it's expired is the current joke. It works among friends who share that reference and lands as confusing or cringe with anyone who doesn't.
If 🅱️ came up in a conversation, these are the emoji people most often look up next — each one explained the same way, with meanings you can actually use and characters you can copy.
