The sound is associated with Timmy Burch from South Park, the animated TV series that introduced the character in the early 2000s. His shouted name became one of the show's most recognisable recurring bits, and short clips spread widely in meme edits, soundboards, and reaction videos. People still use it because the delivery is immediate and unmistakable, making it easy to drop into fast comedy edits as a loud non sequitur. It often fills the same reaction role as a bruh clip or a buzzer in quick punchline formats.
