This sound is based on the famous Titanic melody associated with the film's emotional love theme, but the meme version is known for being played poorly on recorder or flute for comic effect. Online, it spread through short video edits, reposts and soundboards because the contrast is immediate: viewers expect sweeping romance and get a wobbly, low-budget performance instead. It is still widely used when creators want parody sadness, awkward drama or a deliberately unserious emotional beat, much like a buzzer can undercut a moment in a different way.
