The 'I Will Defy Biology and Get You Pregnant' meme is a catchphrase typically paired with images of hyper-masculine characters, most notably Toji Fushiguro from Jujutsu Kaisen or various 'GigaChad' style edits. The phrase highlights a humorous, albeit aggressive, level of confidence or desire, often used within 'stan' culture or as an ironic expression of attraction. It gained significant traction on platforms like TikTok and X (formerly Twitter), where users sync the text to intense phonk music or dramatic transitions. The meme functions by subverting the laws of nature through sheer willpower, making it a staple for ironic 'alpha' humor and fandom-specific inside jokes.
