The 'Blud' meme originates from London street slang, specifically the term 'blood' meaning friend or brother. In the 2020s, the term transcended its UK roots to become a global internet phenomenon used to describe someone acting strangely, confidently, or out of place. It gained massive traction on platforms like TikTok and Twitter, often appearing in captions like 'Who is blud?' or 'Blud thinks he's the main character' paired with photos of animals, athletes, or confusing situations. The meme thrives on irony, using the serious tone of roadman culture to highlight absurd or humorous behavior, cementing 'blud' as a staple of modern digital vocabulary.
