X-rider.com

X-rider is a screamer website from a south korean movie called, Epitaph. The screamer is a dead women who her face is covered in blood and she is smiling. There are no screams actually, is just a loud sound effect from the movie that, in a loop, cause it to be kind annoying.

If you search it on google, you will not find the website. I don't know if the site still activate. But on youtube there are some vietnamese kid who recorded his reaction. Go to youtube, search "Epitaph movie" and go to 39:00 and there she is. It's not that scary actually.
