Francis Bourgeois, born Luke Nicolson, became an overnight internet sensation on TikTok and Instagram in 2021 for his infectious enthusiasm for trainspotting. Characterized by his unique GoPro head-cam setup that creates a distorted, wide-angle view of his joyful face, his videos often feature him cheering as rare locomotives pass by. The meme represents unadulterated passion and the beauty of finding joy in simple hobbies. It is widely used to celebrate nerdy interests or moments of genuine, goofy happiness that transcend traditional social media aesthetics, making it a staple of wholesome internet culture.
