This ta da clip is used online as a general reveal cue rather than being tied to one clearly documented source. Across short-form edits, creators use it to underline a visual payoff, usually after a pause, zoom or fake suspense setup. Its staying power comes from how instantly recognizable the gesture is: the sound tells viewers that the moment on screen is the joke, the reveal or the punchline. It often fills the same editing role as a ding sound effect in simple meme timing.
