No, “Bada-bing” didn’t come from your uncle Vinnie. The absurd exclamation has been an old favorite in some circles, but it was Francis Ford Coppola’s The Godfather that popularized the phrase. James Caan originally heard “Bada-bing!” uttered by his real-life acquaintance, the mob boss of the Colombo crime family, Carmine Persico. Caan improvised his dialogue using the expression, as seen in this clip where he imitates the sound of a point-blank gunshot. “Bada-bing” became so popular, The Sopranos adopted the phrase for the name of the show’s strip club.
