Polite golf applause has been a staple of televised tournaments for decades, where spectators clap softly out of etiquette rather than excitement. Online, the isolated sound became shorthand for sarcastic congratulations, the quiet opposite of crowd cheering. Meme editors use it to deflate a moment instead of hyping it, often as a drier alternative to the sad trombone. Its five-second length makes it perfect for short-form video, which is why it still appears in TikToks, streams and reaction edits.
