A Flash program or video that appears to be a game, a test or a still image. The point is to get somebody to concentrate on the program for a period of time and then all of a sudden a loud scream is heard. Often these screams are coupled with a scary image. These programs are meant to be jokes to scare the hell out of people. These often work because the person is often so involved in the program or concentrating so hard they are totally taken by surprise when the scream and scary image come on. There are many of these programs on the internet and Liquid Generation’s Sabatoge series is a good example of these Flash programs. Some other examples of these kinds of programs are:
A maze game where you can't touch the edges with your cursor. You only get to level 3 and when you are trying to navigate your cursor through a small area the scream starts with a scary image of a possessed woman.
A vision test where you need to trace a large letter with your mouse and not go outside of the lines. Then a scream comes up and a scary image.
"My friend showed me a game and it turned out to be a screamer. It scared the hell out of me."
"That video of the dad having his kid play that maze screamer game is freaking hilarious."
A youtube video or a Flash game used as a practical joke to try and scare the viewer or the player abruptly.
It starts out quiet, so the victim is forced to turn up the volume. After about a minute or two, a maxed out volume scream is heard occupied with a frightening image.
One type of screamer is The Maze. The player has to go through a maze without touching the walls. Once the player gets to Level 3, they get close to the end, and a scream is played with a picture of a possessed woman.
