Ezio Greggio is an Italian television presenter, comedian and actor best known as the long running host of the satirical show Striscia la Notizia, which he has fronted since its launch in 1988. His exaggerated delivery and repeated catchphrases became a staple of Italian popular television, and short clips of his voice later circulated online as reaction sounds. Upapapa survives in that form, shared on soundboards and in chat edits because a single familiar shout can signal joking disbelief without needing any context or explanation from the original broadcast.
