Sirens have been a staple sound effect in film, television and games for decades because audiences recognise the wail immediately without any explanation. Online, this fifteen second version is shared on soundboards as a quick alert noise for edits, streams and prank clips, often paired with flashing lights or a sudden zoom. It sits alongside other siren memes like the social credit siren, which also turns an alarm into a joke about being in trouble. Its popularity comes from that instant meaning, it needs no setup and lands with any viewer.
