The phrase comes from Boris, the Italian television comedy about the chaotic making of a fictional soap opera, where the self-important actor Stanis La Rochelle is a recurring source of diva behaviour and on-set meltdowns. Short clips of his outbursts circulated among Italian viewers long before soundboards made them easy to reuse, and this blunt farewell became a shorthand way to end an argument. It survives because the delivery is instantly recognisable even out of context, and because the Italian wording keeps it punchy for international meme edits too.
