The line comes from Kung Pow Enter the Fist, the 2002 martial arts parody written, directed by and starring Steve Oedekerk. The film redubs and re-edits a 1976 Hong Kong movie, giving its hero an intentionally mismatched, high-pitched voice. In the scene, the sheer size of a pile of nuts prompts the stunned outburst, and the clip later spread through forums, video edits and soundboards in the 2000s and 2010s. Its exaggerated dubbing style made it easy to reuse out of context, so it survived as a shorthand reaction for anything present in ridiculous excess.
