The Red Room is an internet legend about a pop-up ad which appears on the victim's computer. The image simply shows a red door and asks the question "Do you like-" in a recorded voice. Even if the pop-up is closed it will repeatedly appear until the voice is able to finish the question: "Do you like the red room?".
Those who have seen the pop-up are found dead, their walls painted red with their own blood. The legend began as a Flash animation of a boy being cursed after encountering the pop-up.
It's unknown how the story could possibly be told, especially in such detail, since all those who see the pop-up die.
