2 Girls 1 Cup refers to the trailer for a 2007 Brazilian scatological fetish film titled 'Hungry Bitches.' While the original video became one of the most notorious shock videos in internet history, its true legacy lies in the 'reaction video' craze it catalyzed. During the late 2000s, it became a common prank to record friends and family members as they watched the video for the first time, capturing their visceral expressions of disgust and disbelief. Today, the meme serves as a nostalgic hallmark of the early web era, often used to represent situations where someone is forced to witness something they can never unsee or to joke about the shared trauma of early internet users.
