The Red Room is a Japanese urban legend about an internet pop-up that advertises one thing and one thing only: your imminent death. According to legend, The Red Room appears as a red window displaying only the words "あなたは〜好きですか?(Do you like ____?)" which are read in a mangled but supposedly cute voice.
"Do you like ___?" Now, you may be thinking, "That doesn't even make sense! I'll just exit out of this stupid pop-up and end this right here and now!" But no. Once the Red Room has chosen its next victim - there is no escape. The more you try to exit out of the Red Room pop-up, the worse things get.
As you get increasingly frustrated and start madly clicking the exit button as if you can avoid your grim fate, "あなたは〜好きですか?" begins to transform as the words "赤い部屋が" slowly appear. Click by click, the complete question is eventually revealed: "あなたは赤い部屋が好きですか? (Do you like The Red Room?)
At this point, all hope of survival is lost. You can kiss your miserable butt sayonara. Once the full question is revealed, the entire computer screen is enveloped in red and a list of names appears - past victims of the Red Room. What happens immediately after that is unclear, but one thing is for certain: victims of the Red Room commit "suicide," coating the walls of their rooms with their own blood. Hence, the legend of "The Red Room."
