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."

"I love to show my friends screamers so they get scared for a few seconds."

1) A person who makes loud noises, particularly during either sex or physical exercise.

2) A flash program with a massive shift in volume. It will usually start up low so you have to put your speakers up, then will emit a loud 'scream' literally out of nowhere.
1) I had to put a pillow on her head to keep her from waking up her parents, she was such a screamer.

2) That flash program which plays the song really low backwards is a screamer.
