The 'Blood' meme, often represented as the 'Bloods vs. Crips' or 'Red vs. Blue' rivalry, evolved from 1990s gang culture into a lighthearted internet comparison format. In its meme form, it typically features two figures representing the opposing factions, used to ask the audience to choose between two mundane or humorous options, such as Coke versus Pepsi. It became a viral sensation on platforms like Twitter and Reddit as a way to spark playful debates about personal preferences. The meme relies on the visual contrast between the red and blue colors to signify a deep-seated, albeit often ironic, loyalty to one side or the other.
