The 'Cereal or Milk First' debate is one of the internet's oldest and most persistent low-stakes arguments. It centers on the proper etiquette of breakfast preparation, where pouring milk before the cereal is widely considered a 'culinary crime' or a sign of chaotic behavior. The debate became a staple of social media platforms like Twitter, Reddit, and TikTok, often used as a litmus test for someone's personality. While the origin isn't tied to a single image, it has evolved into various templates comparing the 'normal' method (cereal first) against the 'heretical' method (milk first), often using reaction images to express shock, disgust, or superiority.
