The 'When Ancestry.com Says' meme is a satirical take on the surge of commercial DNA testing kits and the dramatic way people react to their results. It usually highlights a person discovering a minuscule percentage of a different ethnicity and immediately adopting exaggerated stereotypes or a new personality based on that finding. This meme gained massive traction on platforms like Twitter and Reddit, serving as a humorous commentary on modern identity and the obsession with genetic heritage. Whether it's claiming royal blood or a new nationality based on a tiny data point, the template perfectly captures the irony of a 1% discovery changing someone's entire worldview overnight.
