A shock site is a form of screamer that uses disturbing imagery, commonly pornography and graphic content, to shock the viewers. Just like traditional screamers, shock sites have as a goal to shock the viewers with unexpected content. Some good example of shock sites are 2 Girls 1 Cup, Jarsquatter and Goatse. These websites have gained a high level of popularity and are often used as a way to prank people.
Shock sites slowly started to spread around the Internet in the late 90's, when they were not as common as they were now. The first shock site to be widely spread across the web was 2 Girls 1 Cup. This 1-minute clip of two women playing in their feces made a huge success. Since then, some more shock sites made surface on the Internet, some of them taking inspiration from 2 Girls 1 Cup, and other ones being far more disturbing.
Shock sites have caused a new trend to make surface. People have started to record themselves or someone else's reactions to these websites, and post them on social media and video sharing websites like YouTube. Reaction videos are widely known across the Internet.
