Rob Walker's March 7 "New Old Thing" column is called "Great Moments in Gibberish." There are some good videos in the piece, including this one, called Prisecolinensinenciousol.
Prisecolinensinenciousol, a parody by Adriano Celentano for the Italian TV programme Mileluci is sung entirely in gibberish designed to sound like American English.
Both Celentano and the currently ascendant YouTuber known as smokahontas are (whether intentionally or not) riffing on the tradition of "double-talk" — a comedic use of nonsense syllables to mimic language that dates back at least to the Vaudeville era.
