The 🅱 Button Emoji meme, represented by the Unicode character for the Blood Type B symbol, gained massive internet notoriety in late 2016. Originally used in gang culture to replace specific letters, it was quickly adopted by ironic meme communities like r/dankmemes. It became the definitive symbol of 'Deep Fried' humor, where users replace consonants in words to create surreal and phonetically aggressive captions. The meme is often paired with high-contrast filters and lens flares, serving as a cornerstone of post-ironic internet culture where the symbol itself acts as a punchline for nonsensical or high-energy situations.
