This kiss effect is credited to Canine Casanova, the Pluto cartoon released on 27 July 1945, where exaggerated sounds helped sell the dog's romantic antics without dialogue. A version of the recording later circulated in sound libraries under a descriptive wet, smacky kiss title, credited to Hollywood Edge. Editors kept reusing the tiny clip because cartoon kisses remained a universal visual gag. It now appears in meme edits, animations and reaction videos whenever a creator needs an instantly readable smooch that audiences understand across languages and generations today.
