Pierino is the mischievous schoolboy at the centre of countless Italian jokes, brought to the screen by actor Alvaro Vitali in a run of popular comedy films in the late 1970s and early 1980s. The character became shorthand in Italy for cheeky, badly behaved humour, and short clips of his voice later found a second life online. This vaffanculo shout now circulates mainly as a WhatsApp audio and reaction sound, shared between friends when a blunt, funny refusal says more than a typed reply ever could.
