Ice cream truck music became a shared cultural shorthand in the United States and other countries where mobile vendors play a repeating chime tune to announce their arrival on residential streets. Online, the melody was adopted for memes, edits and soundboards because a few seconds are enough for viewers to understand the joke without any setup. It now appears in summer montages, nostalgic throwbacks, prank videos and ironic horror edits, where the cheerful tune contrasts with what is actually happening on screen.
