The Delta symbol has long been used as shorthand for change, which makes this short clip easy to recognise even without a clear original source. Online, creators have adopted simple symbol sounds like this one for memes, edits, and reaction videos, where a brief audio cue can signal a turn in the joke or the story. Its appeal comes from that simplicity: it carries no dialogue to translate and no long musical phrase to fit, so it works across different formats and languages and remains useful as a quick marker for a shift.
