Agor.io
From Screamer Wiki
Similar to most screamers, this page displays a flashing picture of Jeff the Killer along with an ear-piercing scream, and if you try to close the page a pop-up with YOU SCARED BRO LOL appears. Meant for people who accidentally mistype the popular game "agar.io" People with epilepsy should not look at this page and try to be careful when typing agar.io
