The clip circulated on YouTube Shorts tagged as a Samsung alarm sound, credited in its file tags to NOMEN tokyo, and was reposted on soundboards under the joke title How to Make a Bomb 101. The name is not a real tutorial, it refers to the prank described by uploaders: set the alarm, let it ring, and film the reaction. Short-form creators kept reusing it for wake-up pranks and countdown edits because the harsh alarm tone cuts through phone speakers and reads instantly as danger, panic, or a timer running out.
