“Bazinga” became widely recognized through The Big Bang Theory, where it was used as Sheldon Cooper’s signature prank catchphrase. The sitcom premiered in 2007, and the line quickly spread through clips, GIFs, and meme culture because it was short, distinctive, and easy to quote. Online, the sound is still used to mark a weak joke, a sarcastic reveal, or a deliberately cheesy punchline. Its staying power comes from how instantly people recognize the word and the smug comic timing that comes with it.
