Zalgo

"Zalgo" is a creepy internet phenomina where one usualy alters a picture to make it extremely gorey.

Most of the time a perso making a zalgo picture removes the eyes in place of bleeding black orbs, and adds black tentacles. You can also use "Messy text" to make your post/page look like it has been attacked by "Zalgo"\

Also see "Project Zalgo" for more information.
