Online screamers became a staple prank format in the early 2000s, spreading through forums, email chains and flash sites that promised something calm before delivering a loud scream and flashing image. This autoway.jp version follows that same pattern and has survived as a short, shareable audio clip on soundboards, where the scream alone carries the joke without the visual. Creators reuse it in edits, gaming clips and reaction videos because the sudden volume spike is instantly recognisable, even for viewers who have never seen the original jumpscare page.
