 When Gaff talks to Deckard in the Japanese restaurant he speaks  partly in Hungarian, he says: "Azonnal kövessen engem" which means  "Follow me immediately", and "Lófasz" which can mean "bullshit" or  "no way", although more rude (verbatim: horse penis). Evidently,  Hungarian moviegoers find this fantastically funny. Gaff continues  in Hungarian. He says, "Nehogy már, te vagy a Blade Runner," which  means, "No way, you are the Blade Runner." After this, he switches  to another language.
