Che sta a fa is a Romanesco expression meaning what is he or she doing, and this clip pairs that everyday Italian question with the voice of Paolo Bonolis, one of Italy's best-known television presenters. The line has circulated online as a short reaction sound, shared on soundboards and in Italian meme and commentary videos where a single confused question says more than a longer explanation. Its appeal is its familiarity and timing, so it remains a handy shorthand for disbelief whenever Italian creators need a quick, recognisable response to strange behaviour.
