The clip comes from the G20 summit in London in 2009, where Italian prime minister Silvio Berlusconi shouted across the room to US president Barack Obama during an official photo moment. Queen Elizabeth II was caught reacting to the noise, which helped the brief exchange spread far beyond political news coverage. Clips and replays circulated online for years, and the shout became a standalone meme detached from the summit itself. It is still used because the contrast between a formal world leaders gathering and a loud, casual greeting remains instantly funny.
