"What What (in the Butt)" is a viral music video released by Samwell in February 2007 that became one of the most iconic pieces of early YouTube history. Known for its surreal visuals, catchy hook, and Samwell's flamboyant performance, the song quickly ascended to legendary status, even earning a parody in a 2008 South Park episode. The meme typically uses stills from the music video to express shock, confusion, or to reference the song’s absurdist humor. Over the years, it has remained a staple of internet nostalgia, representing the experimental and unpredictable nature of early web content.
