The 'Hype Train' meme is a visual metaphor for the rapid buildup of excitement and collective anticipation surrounding a specific event, product, or cultural phenomenon. Often depicted as a literal locomotive speeding down tracks, it represents a point where momentum becomes unstoppable and everyone is encouraged to 'jump on board.' The term originated in gaming and tech circles to describe the frenzy before a major release, but it has since expanded into sports, finance, and pop culture. It is frequently used to mock excessive enthusiasm or to celebrate a genuine community-driven surge of interest, often featuring labels on the train itself or the obstacles it inevitably crashes through.
