The 'Neil deGrasse Tyson Reaction' (or 'Watch Out, We Got a Badass Over Here') originated from a 2011 interview on the 'For the Love of Science' YouTube channel. In the clip, the astrophysicist describes Isaac Newton's inventions and makes a distinctive hand gesture to emphasize Newton's brilliance, which the internet quickly reinterpreted as a sarcastic reaction to someone acting overly tough or boastful. The image became a staple of early 2010s meme culture, often rendered as a black-and-white vector outline or used as a high-definition reaction image. It remains the go-to template for mocking people who think they are more impressive or rebellious than they actually are.
