Timmy is a recurring South Park character known for loudly saying his own name, which made clips like this memorable to viewers of the show. The series debuted in 1997, and short Timmy audio moments have circulated for years in meme compilations, reaction videos and soundboards. The clip stays popular because it is instantly recognizable, easy to place as a punchline and funny even without setup. It fits the same quick reaction tradition as sounds like Noot Noot - Pingu, where a brief character catchphrase does all the work.
