The 'He was a boy, she was a girl' meme stems from the opening lyrics of Avril Lavigne's 2002 pop-punk anthem, 'Sk8er Boi.' While the original song describes a simple social mismatch between a skater and a ballet dancer, the internet transformed the phrase into a template for absurd and ironic pairings. Users often post images of two completely unrelated or bizarre entities alongside the lyrics to mock the follow-up line, 'Can I make it any more obvious?' Since its resurgence on platforms like Twitter and TikTok, the meme has evolved into a versatile format for highlighting unexpected contrasts, fictional 'ships,' and nostalgic humor.
