The Jimmy Fallon meme typically centers on the host's high-energy reactions and signature 'over-laughing' during interviews on The Tonight Show. Whether he is slapping his desk, pointing at a guest, or doubling over in laughter, the template has become the internet's go-to shorthand for someone who is exaggerating their amusement or being a 'sycophant.' It first gained traction on platforms like Reddit and Twitter as a way to mock people who laugh too hard at mediocre jokes or to represent the ultimate 'hype man' energy. Today, it remains a staple for reaction images, perfectly capturing that moment when you need to show forced or exuberant enthusiasm for a comedic situation.
