Daffy Duck first appeared in Looney Tunes in 1937 and quickly became known for his greedy, scheming personality and distinctive lisping voice. His manic laugh became one of his trademark reactions, used whenever he believed he had outsmarted Bugs Bunny or another rival. As classic cartoons were clipped and remixed online, the laugh spread beyond television into memes, reaction videos and gaming edits, where it now signals smug confidence just before a downfall. Its instantly recognisable cartoon sound keeps it useful across generations of viewers.
