The Trump Baby Balloon first gained international fame in 2018 during Donald Trump's visit to London, where a massive six-meter-tall inflatable depicting the former president as a crying infant in a diaper was flown over Parliament Square. Designed by Leo Murray as a form of non-violent but highly visual protest, the balloon quickly became a global symbol of political satire and resistance. In internet culture, the image is frequently used to mock perceived childish behavior, public tantrums, or oversized egos. It transitioned from a physical protest prop to a digital template that users deploy to satirize various political figures or personal situations involving dramatic overreactions.
