The '1 Hour of Silence Broken by Sound Effects' meme refers to a popular subgenre of YouTube videos designed to bait viewers into a state of calm before startling them with sudden audio. The trend typically utilizes a static image—often featuring a popular internet personality, character, or the 'Vine Thud' cat—alongside a progress bar. These videos became a staple of ironic shitposting culture, evolving from simple pranks to complex edits where the sound effects range from the 'Metal Pipe Falling' to the 'Taco Bell Bong.' It plays on the humor of subverted expectations and the absurdity of waiting an hour for a split-second payoff, making it a favorite for Discord servers and social media trolling.
