Mereana Mordegard Glesgorv

Mereana Mordegard Glesgorv is supposedly a cursed video on YouTube. If you search for it once, you get nothing. Searching for it a couple of tries, you will actually find a twenty-second video that consists a man staring at you with a red overlay for several of seconds before the camera cuts to him in center, now grinning for the last two seconds of the clip.

Original Story
According to the Creepypasta Wiki, there was supposed to be an extended two minutes of the video, which led 153 people to gouge their own eyes out and mail them to YouTube's main office in San Bruno. Other people who had watched the video committed suicide in different ways. YouTube only put up the video for about 20 seconds. During the 45 seconds of the clip, one YouTube staff member started screaming. The other people were in the same room as him. When the video was finished, the members turned off the video for him, and all they could hear was a high-pitched drilling sound.

The man in the video was never identified, and the person who had uploaded the video was never to be found.

Origin
The 20-second video was originally uploaded onto YouTube around April 19, 2008 by YouTube user, "erwilzei" with a gain over 1 million views. The next day, another YouTuber, "cagalhaodemerda" uploaded an extended 2-minute version of the original video, adding a fabricated backstory of the video itself.

One of these videos have inspired many parodies and recreations later on.

Debunkery
The next day after the video was created, a video shows the unedited picture of the man. The man identified in the video is Byron Cortez who lives in the U.S. Virgin Islands.
