The Death of Pedro Ruiz III stems from a 2017 YouTube stunt where Ruiz attempted to prove an encyclopedia could stop a .50 caliber bullet. The incident, filmed by his girlfriend Monalisa Perez, tragically resulted in his death and became a global news story about the dangers of chasing viral fame. On the internet, the event is frequently used as a meme to represent extreme overconfidence, the disregard for basic safety, or 'Darwin Award' style situations. The template usually serves as a metaphor for people attempting risky behaviors without understanding the lethal consequences involved.
