The 'Pluh' sound effect, often misheard from the 'Plug' ad-lib commonly found in trap music (specifically associated with artists like Rich the Kid), became a viral sensation on TikTok and social media. It is typically used as a comedic non-sequitur or a reaction to a confusing or absurd situation, often paired with images of a 'thousand-yard stare' or the 'Pluh cat.' The sound gained massive traction within 'brainrot' meme culture, where it serves as a punchline for nonsensical video edits. Its popularity lies in its short, phonetic punchiness, making it a staple in modern short-form video editing and Gen Alpha internet slang.
